Archer Project Board Power Supply
This board provides 5 volt or 13.8 volt power. may be built up as a 5 v/13.8 v dual power supply. This board has LM317 and make a nice Laboratory bench supply. Thanks...
Running Lights with CD4017
The 555 Astable generates a clock for this circuit, an oscillator giving a square wave output at pin 3 which is counted by 4017 to give a running lights effect. Digital Timers Counters and...
