An H-bridge (full-bridge) driver is quite popular in driving loads such as brushed DC motors and it is widely used in robotics and industry. The main advantages of using an H-bridge driver are high ...

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 ...

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 ...

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 ...

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 ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...

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 ...
