This project was created during the Nordic Workshops 2023 in Kraków.
Tested on nRF52840DK
Note: if you want to use PWM and your board supports it, it will be much better to use hardware PWM.
Pulse-Width Modulation is a method of controlling the average power delivered by an electrical signal. The average value of voltage (and current) fed to the load is controlled by switching the supply between 0 and 100% at a rate faster than it takes the load to change significantly.
After successful building you will be able to see smoothly blinking LEDs: LED1 and LED4:
You can also control the brightness of LED2 with BTN1 and BTN2. It can be turned
off with BTN3 and turned on with BTN4.
