Wiring
On the ULN2003A board, we have only up to 4 inputs to connect
1N1
1N2
1N3
1N4
The signal goes through each input. The lights shown to the right of the board will show the status of each phase. We then connect the other end of the wires to the pins on Arduino starting from 8 - 11
1N1 ---- 8
1N2 ---- 9
1N3 ---- 10
1N4 ---- 11
In addition:
( + ) ---- 5V
( - ) ---- GND
So far, Arduino will power the circuit, but the motor needs external power (battery, or power adapter). I’ve used a battery.
