I created this website in 2004 to showcase my Rototron arcade cabinet and other MAME and BYOAC related projects. The site has burgeoned to include electronics, Raspberry Pi, AVR microcontrollers, programming, CNC and my other hobbies. After over a decade, I decided it was time to spruce up the HTML. My goal was to utilize modern […]
I received a request to make a tutorial on how to use 7 segment LED displays with a Raspberry Pi. This video demonstrates how to hook up and use pulse width modulation (PWM) in Python via the Pi’s DMA hardware to drive dual digit 7 segment LED displays.
A quick tutorial on how to hook up LCD displays to a Raspberry Pi using I²C and control it with Python. Both PCF8574 and MCP23008 chips are demonstrated.
A quick tutorial demonstrating how to interface an HC-SR501 motion detector sensor with a Raspberry Pi and display the result on a 16×2 LCD display. Builds on my previous 2 LCD Display tutorials.
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.
