This simple but effective enclosure will fit any 'classic Arduino' shaped development board - we've tested it for sure with the Arduino UNO R3, Adafruit Metro, and Adafruit Metro Express. It's clear so you can see all your onboard LEDs and silkscreen labels. There are four small screws ...
An Arduino is a development platform used by many development kits that operate using Atmel-based microcontrollers. Arduino doesn’t refer to a particular microcontroller, but rather a platform for microcontrollers.For example: The Arduino Uno used in this tutorial is a kit that has an Atmel ...

FreeRTOS Task for Blink LED in Arduino UNO The OS present inside the embedded devices is called anRTOS (Real-Time Operating System). In embedded devices, real-time tasks are critical where timing plays a very important role. Real-time tasks areTime Deterministicmeans the ...
Since 2015, Infineon has been offering specific shields for Arduino, the open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. Built in line with the standardized Arduino Uno Formfactor, Infineon Shields for Arduino empower developers to conduct fast and in...
Arduino Uno and Arduino Nano are not selected in this project because 1) the RF module and Bluetooth module we are using are all 3.3v powered; 2) We would like to design a PCB and aim to make the walkie talkie in the size of a credit card; 3) Converting the output voltage of a ...
