This microcontroller-based control circuit adjusts the speed of a small permanent-magnet DC motor to one of four speeds as selected by a pair of photosensors.

A microcontroller's internal ADC was inadequate to measure its own supply rail, so a circuit using standard discrete components was devised to do this with just one pin of the IC.

Current source and measurement Figure 7 shows the digital outputs of the microcontroller that connect to a DAC circuit (AD420) with 16-bit CMOS current output using the SPI protocol. With this circuit ...
