The simplest of fan-control schemes an on-off switch is simple but inefficient, because it provides more cooling than necessary most of the time. When The simplest of fan-control schemes — an on-off ...
Using this circuit, you can change the speed of the fan from your couch or bed. Infrared receiver module TSOP1738 is used to receive the infrared signal transmitted by remote control. The circuit is ...
In the old days every instrument or system had a power supply board with discrete, homemade regulators on it to power the system. Then IC’s like the LM7805 series of voltage regulators changed ...
