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 ...
Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...
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 ...
The function of the 555 timer is mainly determined by two comparators. The output voltage of the them controls the state of the RS flip-flop and the discharge tube. It also contains 3 working states.
In this tutorial I am going to create a Police Light themed LED Flashing circuit using the 555 timer IC. My 5-year old son asked me to create a Police Car like flashing light that he can put on top of ...
The NE555 is a popular IC that functions as a timer or an oscillator. It’s an 8-pin IC available in various packages. We are using an SOP-8 package of the IC. Due to the versatile functioning of the ...
