The circuit is a triangle waveform generator that uses as few parts as possible. A 555 timer IC, 2 resistors and two capacitors make the triangle wave. The IC is connected in a 50% duty-cycle astable ...

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 ...

Since its invention over a half-century ago by Hanz Camenzind at Signetics, the familiar 555 analog timer (in league with its updated pin-compatible CMOS descendants) has become an iconic design ...

[Ch00f] finally made a breakthrough with his efforts dimming EL wire. He’s been at it for months and the last we heard his TRIAC idea had sputtered out. Not to be discouraged and with an determination ...

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 ...
