If you have a cathode LED, your black wire will connect to ground instead of 5V. All of the ground pins (marked GND) are connected on the Arduino, so you can use any GND pin you want. The one thing ...

We will be using a simple LED to demonstrate how we can do digital write on python for Arduino. We will connect an LED to pin 3 of the Arduino. The pin 3 is used as an output pin to control the LED.

Most connected IoT devices today are connected to the internet using a Wi-Fi connection. Although a Wi-Fi connection enables remote access to the internet, it has its own limitations. For instance, in ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...

Raspberry Pi GPIO control with Arduino Cloud is a crucial aspect ... The first step is to physically set up the Raspberry Pi by connecting it to an LED and a push button. This simple setup serves ...

LED 2 (representing X-axis right): Connect the anode of LED 2 to Pin 4 of the Arduino and the cathode to GND via a 220Ω resistor. LED 3 (representing Y-axis up): Connect the anode of LED 3 to Pin 5 of ...

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects. In order to program your ...
