This sketch implements binary code modulation (also called bit angle modulation) for a custom soldered RGB multiplex matrix. Multiplexing is a method of signal transmission used to combine several ...

Such chunking is essential if one is using most Arduino I2C libraries, which impose a 32 byte limit on I2C transfers. Chunking is configurable from the master end, and, after much trial and error, I ...

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

The 16-channel 12-bit PWM/Servo Driver, PCA9685, is an ideal module for precise control of multiple PWM outputs that are commonly used to control servos, LEDs, and other devices in applications such ...
