I am a beginner!
I've been trying to devise a very simple circuit to confirm in my mind how capacitors work. The goal is to make an LED flash on and off using a capacitor or two and one or more transistors.
I've tried various things but I'm getting nowhere fast. I've seen circuits online but they tend to involve two LEDs, inductors or other strange setups.
Can anyone explain the theory behind what I'd need to do (without delving into the maths too much please)?
As far as I can tell a capacitor could be used to control a transistor to make it switch off after a second or so.. my problem is getting it to turn back on!
If anyone can describe what needs to happen (logically) in order to make the LED turn on and off that'd be really good!
