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 NU40DK is NUCODE's development kit built around the Nordic Semiconductor nRF52840 — a powerful BLE 5.0 SoC with a 64 MHz Cortex-M4 processor. In this tutorial, you'll install the NUCODE BSP (Board ...

Last time, we learned how to turn a single external LED on and off using HIGH and LOW. This time, we will increase the number of LEDs to two and control each one from a separate digital pin. Let's ...

As a Mechatronics Engineering student at NUST CEME, I’m soon entering my second year. During my summer break, I couldn’t find an internship near my hometown, so I decided to use the time to explore ...

description Write your first Arduino sketch to blink an LED by programmatically toggling a GPIO pin HIGH and LOW with digitalWrite()—your entrée into combining circuits and code.
