Can you tell me what is wrong with my timer. I want it to make a relay open and shut periodically. For some reason it's not working.

SUMMARY
The discussion centers on troubleshooting a timer circuit designed to control a relay. The user confirmed that their output is directly shorted to ground, which is a critical design choice. A suggestion was made to disconnect the output/diode junction from ground to assess current sinking capabilities. Calculations indicate that the 555 timer can sink approximately 11mA, which is sufficient for the intended operation.
PREREQUISITES- Understanding of 555 timer operation
