This is tutorial number 1 from our series of Arduino tutorials and in this part I will talk about blinking an LED using the one already available on the Arduino Uno board or using an external LED to ...

The power LED is on because, well, the Arduino has power! Why is the other LED blinking? Because the Arduino is executing the pre-installed software called Blink.

It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

Official Arduino Example Tutorials: The Arduino computer software is loaded with tons of examples for you to use in your own code or to run through as a learning experience.

In this post, I am going to probe the components and compatibility of a cheapest Arduino Uno Wi-Fi board you can buy for your IoT projects. The UNO R3+WiFi (ATmega328P+ESP8266) board is an unofficial ...

That article discussed the use of memory-mapped LED control registers, buffers, and a clock source, all used to blink an LED without burdening the microcontroller code with the task.
