How to Change 1-Wire Pin

The default 1-Wire pin on Raspberry Pi is GPIO 4. To change it to a different GPIO pin, enter the following in the Raspberry Pi terminal:

sudo nano /boot/config.txt

Find the following content in the file:

dtoverlay=w1-gpio

If you want to use GPIO 17 as the 1-Wire pin instead of GPIO 4, modify it as follows:

dtoverlay=w1-gpio,gpiopin=17

If you want to use multiple 1-Wire pins, enter multiple lines as follows:

dtoverlay=w1-gpio,gpiopin=17

dtoverlay=w1-gpio,gpiopin=27

Press Ctrl + O -> Enter -> Ctrl + X to save the changes and exit the editor.

Enter the following command to reboot the Raspberry Pi, and the changes will be applied:

sudo reboot
