The Arduino software environment, including the IDE, libraries, and general approach, are geared toward education. It’s meant as a way to introduce embedded development to newbies. This is a great ...

This repository contains an Arduino project showcasing master-slave communication using the I2C protocol. With this setup, a master Arduino can send targeted commands to multiple slave Arduinos, each ...

An Arduino demo code for Level shifter (voltage translator) device evaluation board. This demo code shows NTS0304E operation with changing two side (controller side and target side) signal voltages.

The venerable I²C bus has never been more popular. Most modern microcontrollers either have a hardware I²C interface or are capable of bit-banging one in software. Many sensors, AD and DA converters, ...

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, ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

Sometimes there’s just no substitute for the right diagnostic tool. [Ankit] was trying to port some I2C code from an Arduino platform to an ARM chip. When the latter code wasn’t working, he got clever ...

Starting with physical switches, the way we interact with electronic devices has evolved significantly over the years. We moved from switches to touch screens, and research has continued to push the ...

16 channels, Toshiba PHOTORELAY 100V no clicking, no signal bounce. Switch signals on/off, 2 Amps DC or AC using I2C bus. IO extender PCF9535 Allows many devices on single bus ( > 100 channels). Uses ...
