Explore two new Elektor Academy Pro STM32 programming courses, featuring MicroPython and Arduino, as part of the Embedded ...

In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

In this article we will discuss how to build a powerful DC motor driver that can be controlled using a microcontroller like an Arduino or a Raspberry Pi, or even a standalone PWM generator chip. DC ...

The Arduino library provides a very simple way to generate a PWM signal. The only problem is that the frequency is fixed and all you can alter is the duty cycle: analogWrite(pin, value) where pin is ...
