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 ...

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 ...

Milpitas, CA—Many of you are familiar with the venerable 555 timer IC which included a multivibrator and comparator (see here), and gained wide popularity, and some cult status, as a creative building ...
