What is the point of reviewing a cheap timer module, especially if it is based on the ubiquitous 555 timer chip? Recently I got an ‘updated’ version of the common 555 timer relay module. This time it ...

We discussed the breadboard circuit in video #190 (https://youtu.be/wcRuVxXlEKw), but here we have the finished product, including the panelised PCB from JLCPCB ...

The 555 timer IC is an integrated circuit (IC) that is used in a variety of timer, delay, pulse generator and oscillator circuits. In this tutorial, I am going to show you guys how to make an ...

The 555 timer IC is an integral part of electronics projects. Be it a simple project involving a single 8-bit microcontroller and some peripherals or a complex one involving system on chips (SoCs), a ...

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...

When a 555 timer is operating in Astable mode, we obtain a pulse on the output pin whose ON time (Time high) and OFF time (Time low) can be controlled. This controlling can be done by selecting the ...

It’s back! The 555 timer contest wants to see you do something cool with the 555 timer chip. At stake is the adulation of electronics geeks everywhere. Three top winners will be awarded a $150 ...
