7 Stage Binary Counter Display With LED

Description

This Binary Counter LED Display is a very useful and smart electrical stuff. The Circuit uses an IC number CD4042 (7-stage binary counter). By using this circuit, the number of binary digits arrives at 128 bits. Then, with the help of the 7 LEDs, it makes it easy to build instruction. When receiving a pulse signal from the pressure switch.

In this 7 Stage Display With LED, IC will receive pulse signal pin edge goes up to are logic “1” and when liberate switch receive signal pin edge down is logic “0” thus when press switch time that 2 LED2 stick bright. But LED1 switch off which be the show output the two base is 001 and when press switch time that 3 LED1 and LED2 stick bright. But LED3 switch off display is output the base is two be 011 when press switch time builds go to.

As a result, the display will show the Binary Digit goes to continually until arrive in time 129 which LED1-LED7 will stick bright and the integrated circuit will do something reset to begin the count at new zero output every a leg has will logic “0” cause LED1-LED7 switch off to be finished every.
