    LED Chaser

    This is the circuit of a simple LED chaser. The LEDs lights one by one for a period of 1second and the cycle repeats giving the running light appearance. The circuit uses two ICs to drive the LEDs. IC1 (NE555) is the popular timer IC wired in the Astable Multivibrator mode. Resistors R1, VR1...
