This repository contains a simple but essential Arduino sketch used for scanning I2C devices connected to an Arduino board. The script systematically checks each address on the I2C bus and reports ...

First, we have to include wire library for I2C communication which comes with Arduino IDE. #include <Wire.h> Then for I2C LCD, include LiquidCrystal_I2C.h that is downloaded earlier. #include ...

Using hardware I2C on an ESP32? Do you need to connect multiple I2C devices with the same address? Normally, you wouldn’t be able to do that without extra parts, but on the ESP32, [BastelBaus… ...

I had one of those why-didn’t-I-think-of-it moments this week, reading this article about multiplexing I2C on the ESP32 microcontroller. The idea is so good, and so simple, that it’s almost ...

For this purpose I have a DS3231 attached to the Arduino. I can get the ESP32 working with DS3231, time/date-wise. But I can not set 'alarms' for resetting. Because I have now clue how to set alarms, ...

Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...

We are excited to introduce the all-new Arduino Nano ESP32 – a powerful and versatile IoT development board that opens up a world of possibilities. This feature-packed board combines the ESP32-S3 with ...

The Arduino IDE 2 offers plug-and-play support and even debugging without requiring external hardware. The official ESP32 core for Arduino can be used too, and the board is compatible with the Arduino ...
