Raspberry Pi Pico project: Brightness Control using PWM of 7-segments display adjusted by keypad
Using Pulse Width Modulation (PWM) to control the brightness of a 7-Segments display from a Raspberry Pi Pico board. In the movie the display seems to be flashing due to the Pulse Width Modulation. However, when viewed with the naked eye there is no flashing effect. I am using a numeric keypad to select the brightness level (translated into pulse width). For programming, I'm using the Pico C SDK with the Visual Studio Code extension.
