I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

In part one of this series, we looked at the basics of LED lighting sources and their driving requirements. In part two, we discussed why a constant-current buck converter should be your first ...

This is a simple and very effective project circuit which helps to control the speed of a DC motor using pwm and microcontroller. In many applications, it is important to control the speed of DC motor ...

This project demonstrates a closed-loop DC motor control system using pulse-width modulation (PWM) and feedback via external interrupts. The speed is measured using an IR sensor, and adjustments are ...

I have been delving (groping blindfold, more accurately) into the Arduino compiler adaptation code to try to determine how it handles the switch-over between its pwm activities, its set-I/O-to-output ...

I configured TIMER1 in fast PWM mode 15 with OCR1A as top and used the TIMER1_OVF_vect and TIMER1_COMPB_vect ISRs to bit-bang PWM on the chosen pin for the green LED. I mapped temperature to OCR1B so ...
