This is digital volume control circuit that Can be applied to the normal volume of a power amplifier. When press switch S1 adds up the volume and press switch S2 to reduce the volume down. How it works IC1 is a 555 CMOS Timer Single IC will be connected in astable flip-flop model as pulse frequency generator up / down to input pin of the counter IC2-74LS193, through push-bottom switch S1 (Up) and S2(Down). Changing wide of pulse signal from IC1 may replace R1 with potentiometer. To begin with, when we press the switch S1 (increase sound) binary output will …
The digital clock circuit board using LM8365,alarm and relay control, alert 2 times in 24 hour,backup battery power outage. Show dates, months or seconds
This is daylight sensor switch circuit, for control load turn on when have sunlight. use simple circuit LDR,transistor,relay and can use with 12V supply
The digital clock circuit that electronic amateurs are most interested. And The clock ICs that most popular are LM8361, MM5387,
