For the first example, suppose you need to monitor a DC bus voltage using a microcontroller’s ADC input. During normal operation, the bus voltage is fixed at 24 VDC. For this example, the ADC will ...

It had 3 massive circuit boards of discreet logic and they were clearly marked as having been assembled in February 1970, 2-1/2 years before Atari’s. It had a huge 21″ CRT mounted under a 1/2 ...

2. The detailed circuit uses five standard transistors plus passive components to implement the one-pin battery-monitor solution. When the microcontroller decides it needs to know the battery ...
