This circuit emulates the functionality of the classic 555-Timer IC. It was designed using open-source tools and was taped-out in the Skywater 130nm CMOS process through TinyTapeout on April 19th 2024 ...

A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC. In the process of making this circuit, we'll make a pcb design for it. This ...

Today we are going to create a strobe light for the tips of the wings of an rc airplane using a 555 timer (NE 555 or lm 555 IC) this circuit is very easy to make with few components and most ...

We begin with the DC Motor H-Bridge Control project, which uses two 555 timers to create an H-bridge circuit that controls the direction of a DC motor, offering a great introduction to motor control.

The traffic light project is a circuit that uses two 555 timer ICs to control the timing of three LED indicators that provide stop, wait, and go signals.

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 ...

Abstract: This paper proposed a modified 555 timer IC with only two comparators by eliminating the discharge transistor and SR flip-flop. A periodic square waveform can be generated by utilizing the ...
