Arduino USB Infrared Remote Receiver for Kodi

This project uses an Arduino Pro Micro to receive button presses from an old IR remote you might already have and sends keyboard presses via an emulated USB keyboard. I’m using this to control Kodi, but you could use it to send keyboard commands to any program. Hardware used Arduino Pro Micro, like this one … Continue reading Arduino USB Infrared Remote Receiver for Kodi

Arduino interface to MPU9250 / MPU9255 gyroscope, accelerometer, and compass

This post is a quick introduction to get an MPU9250  gyroscope, accelerometer, and compass module (so called 9 axis) connected and talking to an Arduino. I’m using a 5V Arduino Nano, because the description of this module says that it is 5V tolerant. Markings on chip is: MP92 / W864A1 / 1410   The library I … Continue reading Arduino interface to MPU9250 / MPU9255 gyroscope, accelerometer, and compass

Arduino ST7735 SPI 128×160 TFT Display Module

A quick guide describing how to hook up an ST7735 128×160 SPI TFT display to your Arduino and get the library to display something. Here is a link to the module you can purchase at BangGood: Smart-Electronics-1-8-Inch-128-160-Serial-SPI-TFT-LCD-Module-Display-PCB-Adapter-Power It came packaged in in an anti-static bag with a label indicating that it uses the ST7735S IC: … Continue reading Arduino ST7735 SPI 128×160 TFT Display Module

Upgrading Sonoff Wireless Smart Switch Flash Memory (ESP8266)

I’ve been playing around with the ESP8266 based Sonoff Wireless Smart Switch and I really wanted to upgrade the flash from the 1MB it comes with to 4MB so I can re-program it over wifi. I’ve already got custom firmware running on it, but I don’t like the idea of opening it op and hooking it … Continue reading Upgrading Sonoff Wireless Smart Switch Flash Memory (ESP8266)

Raspberry Pi and Arduino via GPIO UART

NOTE: This is an older post, and instead of using a CD4050 it might be easier to use a bi-directional level shifter module. In an attempt to get my Raspberry Pi talking to my Arduino I’m exploring various different options. The first was to just use the USB connection, but that was too simple. So, … Continue reading Raspberry Pi and Arduino via GPIO UART

Arduino Web Enabled Aquarium Controller

This is a project I started a few months ago, but never finished. I got distracted by the Raspberry Pi :). Even though it is unfinished maybe someone could get some value out of the current state of the project. The idea was to create a controller for an aquarium, to measure temperature, measure water … Continue reading Arduino Web Enabled Aquarium Controller
