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 ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

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.

This is the LED 'J' Sequencer, a project I built for my uncle's birthday! It features 20 LEDs arranged to form the letter 'J', which light up in sequence. The "brains" are a trusty 555 timer and two ...

Take a Raspberry Pi Pico and connect a 555 timer to one of its GPIOs. Arrange for the 555 to poke the Pico about 10 times a second. Treat that "poke" as an interrupt. On the interrupt, light the ...

This article is part of the 2022 April 1st series in the Humor topic within our Series Library. The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 ...

You’re well aware of the IC shortage and its impact. Commentators and analysts have provided many explanations, including unexpectedly high demand, capacity limitations, Covid, and too much reliance ...

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 ...

Abstract: The 555 timer IC is a well-known integrated circuit having been widely used as a pulse generator. We propose a circuit containing a single 555 IC, an LED, an inductor, two capacitors, and ...
