Setup

In order to use the LED we need to enable the SPI interface on the Rpi. You can enable it by running sudo raspi-config, or by manually adding dtparam=spi=on to /boot/firmware/config.txt. Enable PWM -> add dtoverlay=pwm to /boot/config.txt I²C fpr RTC sudo raspi-config -> interface -> enable I²C
