Hi,
before I begin I would like to state that I am a complete newcomer to electronics and I am self-taught so forgive my lack of vocabulary.
I looked up a few tutorials for the 555 astable mode.
like this one: 555 and 556 Timer Circuits
I made the circuit exactly as they told me but I keep getting a steady pulse out of pin3 instead of a square wave. I'm using a 9v battery as my supply and an LED on pin3
Here are a few things I already tried:
1. replacing the 555 timer
2. trying Many diffrent values of resistors and capacitors
3. trying monostable mode(it works)
4. the information sheet says there is an astable mode.
I'm really stuck, If anyone has any suggestions for me I thank you in advance
