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 ...

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 ...

Motion sensor circuits are there on the Internet for quite a while now. These circuits are mainly used to drive AC load (like lights, fans) in home automation or IoT projects. It is also very common ...

Anyone who has designed circuits using the 555 timer chip will, at some time have wished that it could be programmed for longer timing periods. Timing periods greater than a few minutes are difficult ...

One of the most common clichés around here is that a piece of equipment chosen for a project is always too advanced. If a Raspberry Pi was used, someone will say they should have used an Arduino. If ...

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 ...

555 timer IC is an electronic component that we use in many electronic projects. It is called a timer because it can be used to control the time for which an electronic device stays on or off. The 555 ...

The 555 Timers Madness Competition has been launched by element14, an Avnet community, in honor of the release of the first 555 timer IC (555 oscillator). Members of the element14 Community can ...

Designed to accommodate pausing and give full control of your timers. This is yet another simple timer module for Defold. It doesn't have either the same ease-of-use or presumably the performance of ...
