Problem: the current circuit design have a servo motor connected directly to a 9V battery via a voltage regulator for power and a 5V signal drawing from an ARDUINO UNO digital pin, but the servo is draining the battery in about a few days which is no good.
I was thinking about incorporating a relay in the design in order to control the flow of current after the servo has completed its movement. The relay would then deactivate and open the circuit de-energizing the servo and wait for the next signal. I’m very new to the whole electronics scene, so I’m sorry if this seems like a novice question?! The coil voltage would need to operate on 3.8V 50mA and control a 5V circuit, but all the relays I’ve found are for 100+ volts. Can those be use for 5V loads? I’m not sure what baring the max Load Voltage has on the min load voltage.
There is likely a code solution that I’m not aware of and that would be best, but a relay would work.
