Over the years, readers have often commented that microcontrollers (or more specifically, the Arduino) are overkill for many of the projects they get used in. The admonition that the creator “Should ...

In the classic configuration and most variants of the astable 555 multivibrator circuit, the timing characteristics are based on the charging and discharging of a capacitor. However, it can be argued ...

This is a simple circuit named 555 Timer IC Testing circuit which helps in testing a circuit using 555 Timer IC.This is a simple circuit named 555 Timer IC Testing circuit which helps in testing a ...

The 555 timer IC is an integrated circuit (chip) which is used in a variety of timer, delay, pulse generation, and oscillator applications. 555 Signals and Pinout (8 pin DIP) Figure below shows the ...

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 ...

This file type includes high-resolution graphics and schematics when applicable. Paul Rako, Creative Director, Rako Studios Back in 2011, Jeff Hamilton contacted Bob Pease, asking for Bob’s experience ...

This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2, and ...
