Toggle switch using 555

Toggle switch using 555
Description: The following circuit works as a toggle switch. The circuit has two stable states, ON and OFF. Once it is ON, it remains ON till you press the switch again. The project has been derived from buildcircuit.com. You can read the original post from this link: http://www.buildcircuit.com/toggle-switch/  Schematic: 555-toggle toggle-switch-basic You can also operate this circuit using a relay. HOW TO USE A RELAY?  In all MINIBREAD projects, we have used the following schematic. When resistor 1K(connected to Base of transistor) gets positive voltage, the relay gets activated.   555-toggle-with-relay The toggle switch circuit on breadboard: Input voltage to TR triggers the relay. toggle21 toggle-on-mini-breadboard WATCH THE VIDEOS:
