A quick tutorial demonstrating how to use the Python rPI.GPIO module to poll inputs and generate interrupts on a Raspberry Pi then create a hex conversion calculator that displays results on a 16×2 LCD display. Builds on my previous LCD Display tutorial.
I received many questions on how to integrate LCD displays with the Raspberry Pi. This video demonstrates how to hook up and display text on LCD displays with a Pi using 2 Python libraries (lcd.py & Adafruit_CharLCD.py).
I received a request to make a tutorial on how to measure temperature and humidity with a Raspberry Pi. This video demonstrates how to hook up and use the Adafruit & pigpio Python libraries to poll a DHT22 temperature/humidity sensor.
