Symbol Keyboard
Test & Tools
Symbol Keyboard
Difficulty

We are already using this Mini Project every day. It’s easy to build and requires only a Leonardo board and a display shield. It’s a Symbol Keyboard, allowing you to easily type symbols and other characters that don’t appear on regular keyboards.

IR Helper
TEST & TOOLS
IR Helper
Difficulty

Infrared (IR) remote controls make life easier. However, each controlled device typically needs its own remote control, making it awkward when you have many devices. The IR Helper can simplify things by emulating different remote controls.

Arduino Learning

Arduino Learning
Difficulty

Arduino® is an open source hardware and software prototyping environment, but what does this mean?

Digital Compass
Test & Tools
Digital Compass
Difficulty

With this digital compass design, you can add an easy-to-read compass display to your off-road vehicle or build a handheld digital compass powered by a battery bank. It uses two modules and three pushbuttons, so it’s easy and quick to build.

Arduino Based LED Tester
Test & Tools
Arduino Based LED Tester
Difficulty

A handy little tool that can help you out if you work with LED’s a lot, especially if you are always trying to work out the right resistor to make them work.

Installing and Setting Up The XC0440 Weather Station
TEST & TOOLS
Installing and Setting Up The XC0440 Weather Station
Difficulty

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.

Stroboscope and Tachometer
TEST & TOOLS
Stroboscope and Tachometer
Difficulty

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.

Arcade Joystick
Entertainment
Arcade Joystick
Difficulty

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.

How to Build a Self-Toggling Relay
Power
How to Build a Self-Toggling Relay
Difficulty

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.

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

How to Make a Thermal Fan Control
Smart Energy
How to Make a Thermal Fan Control
Difficulty

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.

Ultrasonic Garage Door Notifier
Power
Ultrasonic Garage Door Notifier
Difficulty

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.

Battery Powered Fridges
Power
Battery Powered Fridges
Difficulty

Benefits of battery supported fridge freezers and how to charge them from mains, vehicle or solar power.

Metronome
Entertainment
Metronome
Difficulty

We usually think of soldering irons, pliers and oscilloscopes when we think of electronic tools, and while this project may not be useful to the electronics enthusiast we think it's a good way of showing how Arduino based tools can be useful in other fields - in this case for musicians

Arduino Fridge Alarm

Constructing a Wired Infrared Remote Extender
Entertainment
Constructing a Wired Infrared Remote Extender
Difficulty

IR (infrared) remote controls have been around for about 50 years, with TV being one of the first major applications. They are used in many fields, so components and modules for IR remote control systems are widely available. Here’s how to use them to build an IR remote control extender.
