This very simple sketch scans the I 2 C-bus for devices. If a device is found, it is reported to the Arduino serial monitor. This sketch is the first step to get the I 2 C communication working. The ...

🔍 Universal port and I2C device scanner for Arduino, ESP32, and ESP8266 microcontrollers. Automatically detects active ports, connected sensors, and I2C devices with automatic identification. Arduino ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

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 ...

The Challenger RP2040 WiFi is a microcontroller board from iLabs. It combines a Raspberry Pi RP2040 microcontroller with an ESP8285 for Wi-Fi connectivity. The board has two LEDs, one of which is a ...
