How to use momentary switch to blink a led for 5 sec? Answered
Hello, I'm not able to find cheap toggle switch button waterproof that just on/off my blinking led but a 5sec timer can do it.
I'm currently using this to make the led blink :
9014 transistor, LED 5mm, 30K resistor, 510ohm resistor, 22uf capacitor.
I want to add momentary switch to make it blink for 5-7sec.
