Hi,
I've wired up an astable according to this:
555 Timer Astable Multivibrator Circuit; Pulse Generator Circuit
using a 555 chip.
R1 = 10MΩ, R2=1kΩ, C1=100µF, giving f=1.2Hz.
The thing is a get a really weird trace when connecting to the oscilloscope (see attachment) - 2V/div, 0.5s/div.
What could be wrong? I'm pretty sure it's wired correctly - have checked and double checked.
Many thanks,
Froskoy.
