Raspberry Pi and Servo motors to make a motion security camera

A handy tool to have in your Arduino Kit is an ISP programmer.

We saw this project on Instructables, and had to try it for ourselves. Of course, we ended up using all the Duinotech parts we had around.

Build your very own weather station that not only displays the temperature and humidity but also reports the temperature and humidity readings to your Weather Underground account, where you can view the environmental readings from your weather station online, and even view historical logs of the environment temperature and humidity changes over time.

Use a Tapo Hub and one or more motion sensor modules to make an alarm for your home or small office that you can automate and manually control with your phone.

Many off-the-shelf modules have header pins that can be difficult to work with, whether they are facing the right way or are the wrong configuration (vertical instead of horizontal, vice versa.)

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

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.

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.

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

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.

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.

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.

In this project, we explain Anderson 50A High Current connectors and how to use them to make different leads common in camping, caravaning and four wheel driving.

Linux is a wonderful and free, open source Operating System which can be run on your computer as a replacement to windows.

The best thing about at the ATtiny85 IC is undoubtedly its size, but this also makes it difficult to program.

Wax-on Wax-off lighting, just like karate kid! Use this gesture controlled powerpoint kit as a fun way to turn on power sockets around your house.

Make your next album with our next generation music maker device! Using simple electronic components, we have copied the original and well known Atari Punk Console synthesizer to make this unique "cheap-box" musical synth.

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

How to select the best solar panel and battery to power your campsite. Having electric power while camping is becoming increasingly the norm, and more and more is needed to power modern campsites. Whether you are caravaning or pitching a tent from the back of the car; whether you are going solo or taking the extended family; there is a power option for you. From the solar panels to turn sunlight into electricity, to the batteries to store it, to the ways to plug all your things in, we look at how it all works.

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.

This project is all about creating a simple game to test your memory.

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