Im pretty new to electronics, but I tried building this circuit below.
When I power it up the LED turns on, but is solid, no blinking.
When I turn VR2 the LED dims to off, and back up to full brightness like its suppossed to.
However this is suppossed to be a variable blinking LED, adjusted by VR1, however VR1 seems to have no effect. No matter how its turned or adjusted the led just stays on. No blinking.
Is there something wrong with the schematic? Ive tried 2 different pots on VR1, and nothing.
Really at my wits end.
