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 ...

This project demonstrates full-duplex SPI communication between an ESP32-S3 (running Zephyr RTOS) and an Arduino Uno. The goal is to send one full string from the master (ESP32-S3) and receive one ...

Bit banging is a technique for serial communication in which the whole communication process is handled via software instead of dedicated hardware. To transmit data, the technique involves the use of ...

A Microcontroller uses many different protocols to communicate with various sensors and modules. There are many different types of communication protocols for wireless and wired communication, and the ...

Two year ago Arduino launched MKR WAN 1300 board powered by Arduino Zero compatible Microchip Atmel SAMD21 32-bit ARM Cortex M0+ MCU and a Murata CMWZ1ZZABZ LoRa module based on Semtech SX1276 and ...

This project turns the Arduino into an OBD2 on-board diagnostic tester. So, the Arduino can read OBD2 vehicle data and it can read and clear emissions-related diagnostic trouble codes and ...

Apart from understanding the Arduino's code language, one of the most confusing parts about the platform — especially for beginners — is picking the right board to use in a project. Sure, it isn't ...
