All these timing outputs can be visualized and tracked through a 2 digit common anode LED … Nettet30. nov. 2024 · So, the 555 timer IC acts as a square wave generator and generated clock pulses. This input change is to change the shifting time of the Traffic light (LEDs). Then the Clock pulse from the NE555 timer IC goes into the clock input of the CD4017 counter IC. Then the counter IC counts pulse and changes the output line (Q) logic into HIGH or … pince schaublin
