Hello All,
Please help me to run Solenoid using Lipo and i want to connect a charger also to Lipo. So, it will get charge it discharges
You'll need a driver (transistor, relay...) to switch the solenoid from a digital output pin. I'd use a commercial LiPo charger and a 12V DC source, and 2 diodes to route the higher of both voltages to the consumers (solenoid and Arduino).
