Hi, I built the circuit based on the latest version, but the led is not flashing no matter how I adjust R1. Everything else seems to work can adjust brightness by turning R3, R4 seems to be OK too.
I used the following items:
R1 - 100ohm trimpot
R2 - CF 0.25W 3M3 Orange-Orange-Green-Gold
R3 - 20K trimpot
R4 - 100k trimpot
C1 - 220uF 25v
D1 - 1N4004 400V 1A Rectifier
Standard 3mm red LED with 1K resistor in series
So to confirm, pin 4 and 5 of TLC555 timer aren't connected to anything?
What can it be? what can I do to make it work from here?
I checked the circuit and it seems right to me... will double check again...
Any help would be greatly appreciated thanks!
