“This is one of the most basic 555 circuits. This circuit is part of this chips datasheet, complete with the math needed to design to specification, and is one of the reasons a 555 is referred to as a timer …
“Marble mazes (or labyrinths) provide a fun challenge. Their many twists and pitfalls test the player’s speed, control, and accuracy. By the end of this instructable you will have constructed a labyrinth that would have impressed Daedalus, the famous …
“Hello, I see you wan’t to know how to make an NE555 timer based 3 octave synthesizer which fits in a tin. Well, you came to the right place :)”
“This circuit sets up the common 555 timer IC to output a PWM pulse that can be varied by the position of a connected potentiometer. PWM (pulse width modulation) is commonly used to control the speed of motors or brightness …
“555 DC Motor Speed Controller project will control the speed of a DC motor connected to it. This project is built using the popular 555 timer IC.”
“The 555 is one of the most popular chips on the market and hundreds of projects have been created using it. More than 30 billion have been produced and it can do almost anything. This project is a universal 555 …
“I was bored so I started to fiddle around with transistors. The reason this became a LED fade and constant current circuit is just because the parts were at hand and lights in different colors is always cool. Please see …
“Classic AC 230 V Timer project can be used in all application requiring a timer of up-to 3 Minutes to operate or control any AC mains load of up-to 200 Watts. This project is based on the Classic 555 Timer …
“This is an emulation of a 555 timer chip that runs on an Arduino. It can run most basic 555 circuits with no change to the program or the wiring of the emulator. The picture shows the emulator setup to …
“This is a simple design alarm for your winter breaks. With this alarm you need not set time, it detects the day light in the morning and generates beep sound for approx. 1 minute. You need not set time for …
