Thank You all for your kind help in resolving my previous capacitor issues, I now have a new challenge and I am completely stumped. This time it concerns the “555 IC” This thing is driving me mad, I’m trying to get it to run in “astable mode” in order to make an LED blink on and off, its mission impossible! I have viewed at least half a dozen circuits and built them exactly as instructed and the light will not blink on and off, it just comes on and then stays on! I have used the same value resistors, the same value capacitors, the same wires and the same power source as instructed. At first I thought it might have been the timer itself and so I used ten separate 555’s and the result was the same with every one of them, I’ve used different breadboards, I’ve used polarized wires and non polarized wires, I’ve tried different power sources, I even tried using a closing switch and even an LDR, nothing absolutely nothing will make my little LED blink on and off, everyone else’s blinks why won’t mine ? I am so desperate to fix this that as god is my witness I will give $10 to whoever helps me solve this! How can something so simple be so difficult, there must be someone out there who can get to the bottom of this apparent curse, someone step foreword!
The pictures are of my own attempts to build the circuit.
