Walfront 2017 New DIY Bluetooth Smart Robot Car Kit Arduino Line Tracking Obstacle Avoidance Bluetooth Accelerometer Control SCM Car Soldering Kits

The diy smart tracking robot car kit is an introductory electronic kit designed to help kids or electronic, enthusiasts, and novices learn about basic electronic basics knowledge like soldering and simple circuits(photoelectric sensor circuit,voltage comparator,motor driving). The smart kit is designed based on the principle of light reflectivity diference when the light emitting on the white and black items.There is no programming involved, and all of the soldering is beginner-friendly, making it perfect for budding electronic enthusiasts.  Assembling Instruction: Step 1: Welding circuit Electric welding part is simpler, welding sequence according to the principle of component level from low to high, the first welding eight resistance, is important to use multi meter to confirm resistance is correct. Step 2: Mechanical assembly The red line is connected to the 3V positive power supply, the yellow line grounding, excess wire can be used for motor wire. Step 3: The installation of a photoelectric circuit Photosensitive resistance and light-emitting diodes (note polarity) is reverse-mounted on the PCB, and the ground distance is about 5 mm, both photosensitive resistance and light-emitting diodes are 5 mm distance. Finally, you can power test. Step 4: Vehicle debugging The right direction is along the universal wheel direction, if you press and hold the left photo resistor, the wheels on the right side of the car should be rotated and Vise Versa; if the car driving back, exchange the wiring of two motors, if the one side normal and the other side back up, you can swap wiring of back side. Package Includes: 1 x Smart Car DIY Set (Disassembled Parts)
