This project is a solution to power up most of devices or projects required dual (+/-) adjustable power supply. The circuit is based on LM317 positive and LM337 negative voltage regulator. LM317 series of adjustable 3 terminal regulator is capable of supplying in excess of 1.5A over a 1.2V to 30V DC output range, due to TO3 package of IC
Read moreThe Project works as electronic toggle switch. The circuit is based on CMOS CD4013 Flip Flop IC, The circuit has two stable states, ON and OFF. Once it is ON, it remains ON till you press the switch again. A short button press of a tactile switch SW1 latches the circuit ON and another toggles it back OFF. Relay switch
