555 Timer as an A/D converter

I had a Basic Stamp project that needed to measure a nominal 12 volt battery, and I wanted a simple solution. This is the simplest I could come up with. The 555 timer will put out positive pulses. The pulse...

How the capacitor works (in a debouncing circuit)

Understand why the LED does not light up, as the capacitor appears to be bypassing the switch. When the capacitor is fully charged, it does not conduct electricity. Although the individual is a beginner, after 20 hours of studying various...

Two-LED Pilot Light

This circuit was designed on request and can be useful to those wishing to have, say, a red LED illuminated when an appliance is on and a green LED illuminated when the same appliance is off. Any mains operated appliance...

Using microcontroller as oscillator for high voltage power suppy

The design involves using a 555 timer as an oscillator in the high voltage power supply section. There is a query regarding the possibility of altering the design to utilize an output from a microcontroller to generate an oscillating signal...

555 timer music instrument

A simple music instrument/keyboard is created using a 555 timer chip circuit, a piece of paper, and a pencil. The project includes a more advanced automatic music player that utilizes a playing head and a long sheet of paper with...

A control circuit diagram 555 pairs steady mode

The 555 timer in bistable mode has fewer applications compared to its stable and monostable modes. Bistable mode refers to the circuit configuration based on the R-S (Reset-Set) trigger mode. An example of this is a micro-motor reversing control circuit...
