Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

By interfacing it using the Arduino Uno it was fairly easy to program the 6 motors and run them simultaneously. The entire arm is controlled by a smartphone using the HC-05 Bluetooth module, thus ...

Creating a Bluetooth-controlled device with an Arduino Uno and an HC-05 Bluetooth module enables control of lights or even relays to manage AC appliances wirelessly using an Android smartphone.

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

Ever wanted to control LEDs from your phone? This project is an easy way to control six of them with just a few basic components. And in case you wish to replace the LEDs with something else, you can ...

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...

The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

Running a program on an Arduino is easy, but have you tried doing it with a Pi? The Raspberry Pi is powerful enough to be a standalone computer and is also good enough to program a microcontroller.

Here’s what you need to know. How to turn on Bluetooth in Windows 10 Before we dig in, it’s worth noting that Bluetooth will only work in Windows 10 if your hardware supports it.
