A simple and functional circuit for turning a LED on and off with a single button.
For 1W Power Led:
This circuit can working with a DC power supply between 6 and 15V. If it is to be used with 6-8V, the R5 resistor should be 15R 3W as shown in the diagram. For 12-15V, the R5 resistor 27R 5W can be used.
If you want to use this circuit with classic 3mm and 5mm LEDs, you can reach the led resistor calculation page from the link below to calculate the value of the R5 resistor.
