As the ARM processor in the Teensy has two separate I2C channels, it was defaulting to the second one. 96 inch 128X64 I2C OLED, on Arduino Uno, using u8glib library Introduction: OLED (Organic Light-Emitting Diode) is a self light-emitting technology composed of a thin, multi-layered organic film placed between an anode and cathode. Hi guys, Did anyone test what how many of the VL53L0X sensors you can run on the same I2C bus? I only manage to get 4 running reliably using an Arduino Nano v3. Programming ADS1115 4-Channel I2C ADC with Arduino by Lewis Loflin This project will read the voltage from a potentiometer connected to input A1 convert this to a voltage and display the value on the Arduino serial monitor. Hi, terrific article on how to set up an i2c slave using the wire library. Getting Started No matter where you get your keypads from, make sure you can get the data sheet – as this will make life easier when wiring them up. The two I2C lines of each color sensor (SDA and SCL) were connected to unique outputs on the I2C multiplexer. Thi idea it to make an very powerfull and precise IMU for use n RC models or in rockets, and any robots. The output frequency is a bit disappointing (approx.
