Gives Interesting Experience of Assembly - Every components and English instruction of the smart car kits are ready for you. Just build a line following car easily, which is great for hobbyists and learners. Electronic Knowledge the kits Involves - The solder practice kit involves the principle of mechanical structure, electronic, sensor, automatic control, and discipline knowledge. Which is great for students learning. Practice Soldering and Learning Electronics - The smart car kit is fun for soldering. It's also good for keeping up with soldering if you have not done it in a while. Why is the little car always tracking the black lines? The more you practice and thinking, the more your learning. Please Note, it may can be your 2nd or 3rd soldering kit. if you are totally ZERO experience in soldering electronics, maybe the kit is not a good choice for you. Working Voltage: 3V; Finished car size: 104*72*55mm; 2 pcs AA batteries are required (No battery included). You can design your own runway easily by using the black tape (1.5~2.0cm ) or black colored pen. If you have any other needs, please feel free to let us know, we’d love to hear from you! The smart car kit is equipped with the IC chip LM393. Through reasonable circuit design, it’ll follow the dark-color lines automatically. BRIEF INTRODUCTION As we know, the light source has different reflectivity for white and black objects. Here we use red light source and it is reflected back to the photoresistors. By detecting the resistance of the photoresistors, the car can determine if it is driving in the black area. If the detector detects that one of them has drifted, it’ll reduce the voltage on the opposite motor, the car will correct its course to back the black area. The red LED show which motor is receiving power. There is a 16mm wide black runway on the back of the paper instruction sheet ready for testing. If it won’t follow the line, you may need to adjust the potentiometers easily. The process also acquires a better understanding of the circuit design again. EASY AND FUN TO SOLDER When the PCB board taken out, you will find out it is easy to solder because of the clear pads and marks. If you use it as a teaching kit, it would be nice for learners training soldering skills and learning basic electronics knowledge such as the schematic diagram, mechanical structure, electronic basic skills, automatic control, etc. It can be used to an electronics competition kit at school. You’ll have awesome family time if you assemble the solder project kit with your lovely kids, they’ll definitely be proud of themselves when done. 😊 It not only to improve the soldering skills, but give interesting experience of assembly! Please Note ✔ A detailed PDF instruction with pictures is ready for you. Please check if you’d get it from Amz. If the message setting blocks it, ANY NEEDS feel free to reach us, we’ll response you ASAP. ✔ There're 2 and 5 pack smart car kits options, scroll up and have a check. Hope You Like the Smart Car Kit. Enjoy!
