How to Use an RGB LED Module Using the Digital Method. This method only works on Arduino boards with a GND pin next to pin 13. Examples are the Uno, Duemilanove, Mega, and Leonardo. If you have an ...

Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

⚠️ Important: Ensure that all ground connections are properly linked to the Arduino GND pin to maintain a common ground across the circuit.. 🎯 Project Behavior Once powered and programmed, the three ...

This project demonstrates how to control an LED using a push button with an Arduino board. When the button is pressed, the LED toggles on and off. This simple circuit can be a great starting point for ...

Configuring XBee Modules using XCTU. As we have learnt in previous tutorials that the XBee module can act as a Coordinator, Router or an End device but it need to be configured to work in desired mode ...

In this Arduino HM10 BLE tutorial, we will interface HM-10 BLE Module with Arduino Uno to control an LED wirelessly using Bluetooth protocol. ... The Button will send “N” letter to HM-10 which will ...

The RTC module also has just two wire connections. SCL and SDA pins of the RTC module are connected to A5 and A4 pins of Arduino board, respectively. The RTC has a 3V lithium round button cell battery ...
