GRR - this exact circuit was working a week ago, yet I have the urge to make one again today because I managed to find some transistors
Yet, the astable 555 circuit is acting as if it was a monostable circuit - it is only on for a second, then off indefinitely. I have to take out the battery for a few seconds and then connect it again to get the same effect.
It cant be the timer, since I have two - and must be sheer coincedence that BOTH timers broke. And even then, they couldn't have been broken since it is timing something, but not resetting itself...
I have built and the rebuilt and then rebuilt the circuit again, the same result ¬_¬
Attached i have the breadboard of what i am doing - i have tried extending as far as possible to make it clearer for you guys, along with the schematic.
Apart from that R1 is 10k, R2 is 150k and C1 is 10uF, and its not 1hz - its 0.5
