In previous tutorials, we outlined the basics behind physical computing and the Raspberry Pi by activating LEDs and scripts using a simple one button circuit. If you haven't read the previous tutorials please do so, as they include a few points (such as basic Python programming and Board/BCM GPIO numbering) that will be skipped in this tutorial.

Raspberry PI seemed like a good way to do. 1º Modified the file config.txt and I wrote dtoverlay=w1-gpio,gpiopin=27. 2º Turn off the Raspberry Pi. 3º I moved the data wire from gpio4 to gpio27. 4º Turn on the Raspberry Pi. Activate GPIO Via Terminal Commands. Once logged on, at the pi@raspbeerrypi prompt, enter raspi-gpio help to see what GPIO commands are available. A few quick examples: raspi-gpio get prints the state of all GPIO pins. raspi-gpio get X prints the state of GPIO pin X. raspi-gpio set X op sets GPIO pin X as an output. Enabling I2C on the Raspberry Pi using one simple command. Again using raspi-config we can set the state of the I2C port. Using raspi-config has the advantage that it takes care of many additional things for you, and should be upwards compatible. Behind the scenes, raspi-config will edit /boot/config.txt for you, for example, and also update.

The line h = lgpio.gpiochip_open(0) opens /dev/gpiochip0. Then lgpio.gpio_claim_output(h, <pin num>) sets the pin as an output. The lgpio.gpio_write() function drives the GPIO pin to HIGH or LOW to turn the LED on or off.
