adcbasics

This example demonstrates how to use Freenove ADC Chips PCF8591 and ADS7830 with Raspberry Pi and Python to create a digital LED dimmer with a potentiometer.

blink.py

Basic tutorial - how to use Python 3 and gpiozero to control LEDs on Raspberry Pi.

buttonbasics

This example is an introduction to how to use buttons with Raspberry Pi GPIO.

buttonblocking

This example demonstrates how to implement a simple software-based button blocking/priority technique with Raspberry Pi GPIO and Python. The concept is demonstrated with a servo motor but can be applied in other settings as well.

buttons.c

This 2-part Raspberry Pi GPIO tutorial shows how to correctly use buttons with wiringPi. While I use the buttons to control LEDs, you can use the same approach with any other electronic components (or code in a subroutine/function in general).

classicsnakegame

This is a beginner tutorial/intro to Python programming on Linux using the classic snake game as a learning tool.

joystick

This tutorial demonstrates how to use an analog joystick with Raspberry Pi and Python, including how to compensate for drift.

lcddemo

This example shows how to use the LCD1602 I2C display and the HC-SR04 sensor with Raspberry Pi using a multi-threaded approach.

ledpatterns

This example demonstrates how to use Raspberry Pi to blink multiple patterns using multiple LEDs.

pwmleds

These examples demonstrate how Pulse-Width Modulation is used with Raspberry Pi and gpiozero to regulate brightness of LEDs. Both calculated and lookup table methods are shown.

remoteled

rgb-primer

Code base for an RGBLED tutorial with Raspberry Pi.

ultrasonicsensor

This example shows how to use the HC-SR04 Ultrasonic Sensor with Raspberry Pi and Python gpiozero.
