I have a very simple circuit which consists of a battery, a load (lamp), and a button (on-off).
I want to a very simple and cheap (without Arduino or microcontroller) way to open and close the circuit automatically when the button is on and stop when button is off.
Press (ON), the lamp lights up (close) then after 2 s the lamp goes off (open) automatically. Repeat this process continuously untill I press off so the circuit is open and the light off.
Battery voltage: 7.4 V @ 1 A
Lamp power: 3 W
I want it to be like this:
