The assembly steps:
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. Press and hold the right photo resistor, the wheels on the left side of the car should be rotated, if the car driving back, can also
exchange the wiring of two motors, if the one side normal and the other side back up, as long as you can swap wiring of back side.
