Here's another easy to build project similar to the LED tester, and using the same hardware.

Control some dazzling RGB effects with ESP8266 and Vue.js Web App! Want to decorate your loungeroom or living areas with cool lighting effects from your mobile phone? With this kit you can!

Not just a great project for the coming holiday break, this compass can be used to find your way home.

Have you lost or broken the controller for your christmas lights this season?

Even individuals who aren't technologically inclined will find the XC0440 Wi-Fi Weather Station to be an accessible yet comprehensive tool. We demonstrate just how simple it is to install and set up.

So you’ve just finished building your Arduino project, and it’s happily running off the USB lead hanging out of your computer.

Stroboscopes and Tachometers are handy tools for measuring how fast an object like a flywheel is spinning. This Stroboscope/Tachometer is easy to build from a few Arduino modules and other parts.

There's a lot of arcade emulators out there that can run on many computers including the Raspberry Pi so it only makes sense to play these emulators on some authentic hardware. Here we'll show you how to build an arcade style joystick using our new Arcade Pushbuttons and Arcade Joystick. We've got a Leonardo main board to emulate a USB keyboard so it can be used with any software that you can play with a keyboard. Just like any other Arduino design, it can of course be customised to more buttons or even mapped to different keys. We've built ours in an ABS enclosure for portability but there's no reason you couldn't mount the controls directly to an arcade cabinet or even a coffee table.

We are very excited to get the chance to play with our new LoRa Shields, and test just how far we could get a signal using LoRa technology.

Build a simple alert that speaks or chimes when people come within range

Here’s a simple circuit, using just one relay and a handful of passive parts, that allows you to toggle (switch on or off) the relay off and on with just one pushbutton. It demonstrates some of the finer details of working with relays and can be used to control a wide range of devices. Over the years, we have had several requests for simple circuits that allow a relay to be switched on and off by pushing a button. Some readers sent in suitable circuits, but they all involved multiple relays.

There's a heap of modules and shields for controlling power with Arduino, for example the XC4488 MOS Driver, XC4472 Motor Driver Shield or even the XC4418, XC4419 or XC4440 relay modules.

We show you how to set up a HDMI extender to connect your TV or monitor to devices like game consoles, media players and surveillance systems over longer distances than a regular HDMI cable would allow.

Turn your living room into a real life game show and have fun playing with your family and friends! Prepare some mp3 files to play and try to score the most amount of points with an automatic game app on the raspberry Pi. See who has the most musical knowledge between songs of today and yesteryear.

We cover some misunderstood or just lesser known servicing products to help your workshop game along.

Using our Arduino-compatible GPS module and TFT Screen, this project displays basic GPS information such as longitude, latitude, altitude, speed, and distance travelled from point A to B.

This project demonstrates how two modules can be combined with a bit of extra circuitry to do a useful job. The result is a circuit that will power a load, like a fan, when the ambient temperature exceeds a set threshold.

Here's a project that uses two Arduino boards to communicate wirelessly - the first Arduino reads a soil moisture sensor and a temperature and humidity sensor, and sends the data to a second Arduino that displays the data in a graph and text.

The Garage Door Notifier monitors the status of your car and garage. It has an ultrasonic distance sensor that, with the correct placement, can detect a few different states.

While most phones have the ability to display the local time throughout the world, you may not always have access to an internet connection.
