hi all,
im new in circuit - trying to understand how does the circuit in this dettol no touch soap dispenser works.
i've currently dismantled the parts looking at the circuit but still new
anyone can help to explain how does the circuit works
from what i see there are:-
1) 1 yellow + 1 green wires connecting to the sensor
2) 1 brown + 1 white wire connecting to left side of the pump
3) 2 yellow to the top side of the pump
4) 2 green to the right side of the pump
5) 1 red + 1 black to the battery
All this wires are soldered on a circuit block
Would greatly appreciate if someone can help me out in the basic understanding how this pump works.
Thanks all !
