Here we have 555 adjustable timer with two alternate blinking LEDs. Pin 3 of 555 IC can source or sink the current. When output of pin 3 is enabled, it…
We can vary timing cycle (duty cycle) of 555 timer by using variable resister instead of a fixed resister. It uses a readily available 555 timer integrated circuit (IC) to…
A 555 timer LED flasher is a simple electronic circuit that can be built to make an LED blink on and off. It uses a readily available 555 timer integrated…
