For testing I've used the Arduino nano to emulate two devices, one I2C photoresistor sensor and one SPI PWM LED. These devices, for example, could be two different attiny85; but as the atmega368p is ...

I'm using an Arduino Nano RP2040 and trying to use an I2C LCD display (connected to the default SDA and SCL pins) with CircuitPython but when creating the busio I2C class (using the default SDA and ...

My first thought was to use an Arduino Nano to test the sensor module through a special Nano I 2 C shield lying around. But later I decided to try the Seeeduino Nano as it provides a dedicated I 2 C ...

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, ...

Step-by-step guide on designing and programming a custom I2C slave sensor device using Arduino.

You are probably already familiar with using shift registers like the 595 series for port expansion. There can be benefits to using an I2C device instead.

In the previous two HID articles, we talked about stealing HID descriptors, learned about a number of cool tools you can use for HID hacking on Linux, and created a touchscreen device. This time, l… ...
