Monostable multivibrator circuit diagram and its working. It can be used as timers, delay circuits, gated circuits etc. Read this post for more details about its circuit, operation and uses.

We must admit that we’ve been guilty of using a microcontroller to make two LEDs blink alternately in the past. It’s not the worst transgression, but it stems from our discomfort with analog circuits.

While choosing an op-amp buffer, some sources of negative supply were considered, because the buffer op-amp had to provide true zero voltage on its output. In reality, a typical rail-to-rail output op ...
