Review on NE555 Switch Adjustable Module Shield by Frank Garahana
Modifiable for power converters
NE555 5V adjustable time delay module works as advertised. Soldering a 1000uF cap onto an existing 100uF cap introduces a time delay of nearly two minutes. I measured it at one minute and 55 seconds. Draws almost no current until the relay latches. Then it consumes about 60 milliamps.
- Increasing the capacitance of C1 can increase the delay time
- I will add later
