One way around the problem of getting a fast response from a microcontroller is to move the problem away from the processor. In the case of the ESP32 there are some built-in devices that can use GPIO ...

In the previous chapter, we stored the current state in a variable and switched the LED operation mode every time the button was pressed.The signals sent to the LED so far have been of two types: HIGH ...

What sorts of things do you use PWM for? There are lots of very clever uses for PWM. However, there are two applications which account for most PWM applications - voltage or power modulation and ...

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 ...

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 ...
