sudo nano /boot/config.txt

add this in

dtoverlay=pwm-2chan

On the Raspberry Pi, add dtoverlay=pwm-2chan to /boot/config.txt. This defaults to GPIO_18 as the pin for PWM0 and GPIO_19 as the pin for PWM1. Alternatively, you can change GPIO_18 to GPIO_12 and GPIO_19 to GPIO_13 using dtoverlay=pwm-2chan,pin=12,func=4,pin2=13,func2=4. Reboot your Raspberry Pi. You can check everything is working on running lsmod | grep pwm and looking for pwm_bcm2835
