I am doing a water plant project. I need to control multiple solenoid valves with my micro controller circuit using relays. When I connect more than 4 solenoid valves (12 V) with a 15 V adapter it will cause a voltage drop and the solenoid valves are not working.
- Why does this happen and how can I fix this problem?
- How can I connect multiple solenoid valves (ex:64 solenoid valve) with a micro controller using relays?
