Creating flashing and fading led effects using ic 555 circuit the first figure shows the basic configuration associated with 555 ics here it is connected as an astable multivibrator. In this project we will show how to build a simple led flasher circuit using a 555 timer chip. The led brake light has a set of 3 3 led bulbs 3 parallel sets of 3 series leds and 220 ohms resistance. Using short length of jump wire connect pin 1 negative to the bottom row of the breadboard ground.
