The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15. While they function as normal digital pins that can switch a component either ...

and use the “analogWrite” command to control the duty cycle, as shown in the below experimental sketch prepared for Arduino and ATtiny85: int PWM_pin = 9; // LED pin for Arduino Uno (D9) //int PWM_pin ...

Here’s an Arduino library that will let you drive a ... LED example seen in the video after the break. His setup doesn’t use expensive LED drivers, but instead utilizes 595 shift registers ...

If your Arduino runs out of I/O lines, you can always add one of the several I/O expander chips that takes a serial interface to set its several pins ... serial to PWM devices using an FPGA.

Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels ... of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Here, the three LEDs are directly ...

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 ...
