The assembly steps:

The first step: Part of the circuit welding

First we should solder eight resistors, do not forget to use a multimeter to confirm their resistance. Some other polar components, such as triode, led lights, electrolytic capacitors, etc.. These components need to refer to our picture to the direction of welding, welding capacitors, the short pin is negative. When welding the LED, the long pin is positive. Note that the welding time can not be too long, which may burn the components, D4, D5, R13, R14 can be temporarily not welded, integrated circuit chip can also be temporarily not inserted into the base.

Step 2: Mechanical assembly

First of all we need to use screws and nuts to fix the caster on the PCB board, and then paste the battery box on the PCB board through the double-sided adhesive, the battery box on the wire through the reserved hole and then welded to the PCB board, red line connect to the + 3V power supply, yellow line link to grounding, then we need to assemble the wheels, first connected the fixed hole to the paddle of the motor, and then fixed with a screw to prevent the wheels off, finally need to have two wheels with motor to affixed to a fixed position on the PCB board. Finally, the wire of the motor is also welded to the fixed position on the pcb board.

Step 3: Install the photoelectric circuit

Install the photoresistor and the light-emitting diode on the opposite side of the pcb, that is, at the bottom of the car s front, keep the ground distance of about 5mm, and keep the resistance and the distance between the diodes is about 5mm, and finally the power test.

Step4: Car debugging

Plug the two AA batteries into the battery box, and then turn the switch to the "on" position, the car should be kept moving forward
