Review: fun soldering project for kids / young adults - I did this as a father-dauther project with my 9 yo over two evenings afterschool. She had never soldered before and this was just enough of a challenge that it kept up a feeling of suspense to see if it would really work at the end or if some component might have been damaged in the soldering process. General comments: It worked in the end. It gave my 9 yo a chance to build something from a circuit board and a bag of lose parts all the way to a working toy car. The one sheet paper instructions was more of a general guide and the track is on the back so don't throw it away. There are QR codes to scan to download the instruction manual and if you search the name of the product you can find youtube videos showing you how to build it. The videos help with confidence but the actual instructions were more accurate in my opinion. I don't think only having digital instructions is a bad thing because it forces you to look at on a screen which then makes it easy to zoom in on the parts and really see what goes where. Overall, I think it's a pretty good kit. You do need 2 AA batteries (not included). Building comments: Make sure you have the right tools to start. You will need 1) a soldering iron (off desertcart or locally from a hardware store / big box retailer), 2) solder (normally comes with a soldering iron), 3) wire cutters, and 4) a small Philip's head screwdriver. Sort out all of the pieces and pay close attention to the colors on the resisters (small tubes with a wire going out of each end). Match up the colors as exact as possible with the photos and you will be fine. The lights have one positive and one negative wire coming out of it. The positive wire is slightly longer than the negative. If you look on the circuit board there will be one round (negative) and one positive (square) pads. The longer wire goes to the square pad and the shorter one goes to the round pad. The gears on the motors should not be pushed down all the way. Just push them on enough so they stay and turn, this will give you more leeway with positioning the gears for the wheels to connect. I would hold off installing the battery wires and tray until the very end. If it does not work correctly at first, check that there is enough solder to make a good connection for all of the parts. Check that the lights and sensors are allighted together so it can see the light bounce back.
Review: Neat little kit, great for starting out with electronics and soldering - Thought I'd try this little smart car kit, I built one long ago, wasn't as nice as this one though. The kit seems small at first, everything is in a little anti-static bag perhaps 3in by 5in (8cm x 13cm?). Spread the components out and it takes up a fair bit of space. Uh, don't do that though... my cat thinks red LED's are fun to bat around. Let's see... 8 resistors, two transistors, two 10K potentiometers, 4 LED's (2 kinds of red), 2 LDR's, 2 electrolytic capacitors, 2 motors, gear sets and wheels, one battery holder (2 AA) and clicky power button. An LM393 dual op-amp, a nice blue PCB, some wire and a handful of screws. Oh, and a bolt with nut and acorn nut to work as a 'caster' wheel. Plenty to do! The kit comes with a sheet of instructions, one side has an oval track on it so you can play with your smart car right away, while the other side has instructions for assembly, a parts list and a good schematic. If you download the 'Smart Car Instruction' PDF file, it expands on the assembly instructions with good quality color photos, allowing you to visually verify you've got things in the right places, right orientation (electrolytic caps, transistors, LED's and op-amp!). Very helpful. Assembly is straightforward, start with the lowest components (the resistors, usually), and solder them to the PCB as directed, paying attention to the silkscreen for LED & eCap polarity and others as needed. I suppose it took me about an hour, I've been soldering for some years (we won't discuss how MANY years!), and it wasn't difficult at all. The possible problem areas might be the 2 pair of LED/LDR's, which are soldered on the BOTTOM of the PCB, where the solder pads are... so you're kinda soldering them in 'backwards', be sure to leave the leads long on those components so you can get your iron in under them. They need to be long anyways to shine on surface and detect reflected light (or not). The gear sets, axles, wheels and motors were fiddly to assemble, you may need three hands to keep the axle and its supports aligned while you tighten the screw on the other side of the PCB. You'll get it... but you may need to try a couple of times to get it all lined up, I did. Get one screw going good, suddenly the other axle support rotates away from its position. GRRRR! Sometimes blue-tak or masking tape can be very helpful! I have a grumble, I feel the battery holder should be installed LAST, as if you're not really careful centering it and keeping it away from other solder holes/pads, you'll have difficulty placing the four wires to power the two motors. The motor power wires must be inserted into small pads which are very close to the side of the battery holder. I'd really recommend leaving the holder until last, as you'll have more room to get your fingers, pliers, tweezers, chopsticks... whatever... in the area to connect the motor wires. Then solder the two leads for the battery holder, wrap the wires around the PCB, double-sided sticky tape the battery pack in place, and voila! Examining my car, I placed the battery holder a bit off-center (only a teensy bit!), crowding the M1/M2 motor wire contacts. just FYI. Now the really fun bit! Turning it on and tweaking the two potentiometers! This is where I'd like to have a blurb in the instructions describing the potentiometer functionality. Yes, you can figure it out by playing with them, the schematic is very helpful as you can determine that they are bias voltage level controls for the dual op-amp trigger levels. And they interact with each other a little bit, so that can frustrate a less experienced kit builder. Basically, they set the threshold for the two LDR's (Light Dependent Resistors). Depending on how much light is reflected back by the surface, the resistance of the LDR changes, changing the voltage presented to the inputs to the dual op-amp (LM393). If the voltages differ, the op-amp output either goes to Vcc or Gnd, depending in which voltage is higher (wikipedia has a good article on op-amps, check it out). If the output is low (Gnd), it turns on its appropriate transistor and energizes a motor. If the output is high (Vcc), it turns OFF the transistor (PNP) and the motor is de-energized, stopping it. You'll have to tinker with the potentiometer settings to get Mr Smart Car to behave, My experience thus far is to start both pots at dead center, and with the power on, tweak them every so very very slightly CCW (counter-clockwise). My car likes to go to the right preferentially, sometimes I can get it to go left... but generally he likes going around the track in a clockwise direction. Your experience will likely vary from mine. You'll swear it has a mind of it's own though. I took mine into work and set up a huge track using electrical tape on a large table. It ran for several hours with people picking it up and looking, then putting it down to zoom around again. We all had fun! I've enjoyed the kit and will likely order more to give to my friends and their kids, perhaps I can spark their interests in electronics. Or maybe a smart car racing club!

## Features

- ✔【School Science Project】: Smart DIY robot car is the most widely used in school for helping students to learn about the soldering project knowledge of mechanical structure, electronic basis skills, the principle of sensor, automatic control, soldering skill and so on.
- ✔【Its Principle】: As the light reflectivity is difererent when the light is emitting on the white and black items. It uses the photoresistance resistance to tell the smart car is on the right way or not. Smart tracking car can discriminate the direction automatically that it can run freely along the black tracking line.
- ✔【Design Your Runway】: You can also use the 1.5~2.0 cm black electrical tape directly on the ground to design the complex runway. It would be even more fun! This educational kit is perfect for holiday gifting and promotes valuable STEM skills!
- ✔【Easy Soldering】: This smart car solder practice kit is easy to build and the principle is simple. The connection that was clearly mapped and labeled on the PCB board. It's much easier to assemble which is great for students, teenagers, beginners and DIY hobbyists.
- ✔【English Manual】: We provide paper English instruction come with the product. You can scan the QR code in the last picture to get PDF manual. You can also download the Installation Manual on the Product Page Named "Technical Specification" Section (Due To Character Limit).

## Questions & Answers

**Q: Does this come with soldering iron?**
A: Does not come with soldering iron or solder.
You do not need a fancy iron for this kit, 
just an inexpensive basic iron and good quality solder is all you need.

**Q: What tools and materials do you need to build this that are not included? thanks.**
A: Thanks for your question. For better finish soldering the smart car kits, the basic tools and materials are soldering iron, solder wire, tweezers and scissors. If you have any needs, feel free to contact us:-D    Thank you and have a nice day.

**Q: Where can I get another white gear?  Soldering iron touched a gear and melted it.**
A: Might be able to find another one on amazon or through the seller. count the teeth it has and measure the diameter of both the axle and the gear and you can probably search for one on here or google. hobby stores that sell rc cars might be able to help you out as well. or you can have someone 3d print you one.

**Q: Does it matter how the white leds height compared to sensor height? Do they get set flat on the board or how high off the board?**
A: At first glance the bottom LEDs are white but in fact are red. They do sit flush with the bottom of the PCB and the height is controlled by the nut that holds the front off whatever surface you are running your car on.
