Description

Product Description Specification: Name:Tracking Robot Car Photoresistor (LDR) based line following Individual wheel control Chipset: LM393 Material: Electrical components Board Size: Approx. 10.4*7.2cm 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.
