Diy Smart Tracking Robot Car Electronic Kit With Reduction Motor Set

Specifications : Track width : 15mm Color : As shown Size(Length x Width) : appr. 10 x 7cm Power : 2 x AA battery Voltage : 3V 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 multimeter to confirm resistance is correct, D4, D5 R13 R14 can temporarily not welding, integrated circuit chips can temporarily not inserted 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 un Lees meer over de Diy Smart Tracking Robot Car Electronic Kit With Reduction Motor Set van huismerk in de productgroep elektronica
