A set of guides to get you up an running as quickly and as easily as possible.
Arduino development boards are great devices for embedded control. At the low end are the low cost ATMega328 based Arduinos, such as the Uno, Nano, and Pro Mini. At the other end of the scale there are the high priced but more powerful Arm based devices, such as the Due. But sometimes your application may…
Throw out those candles and opt instead for an Arduino sketch to light up those Pumpkins this year. With our simple sketch and the exclusive library it couldn’t be simpler to take your pumpkin to the next level! And remember, don’t throw out the flesh or seeds! We made a lovely pumpkin pie and…
Although you may have never heard of the ESP8266, it has quietly been a huge success in the microcontroller world due to it’s impressive spec and incredibly low price. It is a small wireless microcontroller with built in Wi-Fi (802.11) capability, meaning that it can not only connect to most Wi-Fi access points, but is…
The ATtiny84 and ATtiny85 microcontrollers are great little devices when you need the flexibility of a microcontoller in your project but don’t need all the bells and whistles of the more complex microcontrollers found in common Arduino boards, such as the Arduino Mega or Uno. That said, for such a small pin count they are…
One of the questions we commonly get asked is how to go about using an Arduino to control a motor from a potentiometer. Lots of people out there would like to do this but just don’t quite have enough programming knowledge to get an Arduino to do this. So to compliment the release of our…
LED light cubes are a hugely popular and fun project and with the help of the Hobby Components kit you will have all the parts to build your very own. Building on the popular 8x8x8 cube kit (HCKITS0022), we decided to create a through-hole version for those of you who are better suited to this…
Access your microcontroller from anywhere in the world (Part 1) Microcontrollers are an amazingly cheap way to automate and control the world around you, but in a world where a Wi-Fi connection is available almost anywhere it has not always been as proportionally cheap to get your microcontroller project connected to the outside world. That…
Access your microcontroller from anywhere in the world (Part 3) Basic server example In this example we are going to configure the module as an access point so that Wi-Fi clients such as PCs, tablets, or smartphones can directly connect to it. We can then serve a very basic web page to the connected client….
Access your microcontroller from anywhere in the world (Part 2) Requesting a web page over a TCP connection Now we are connected to the world, let’s try requesting a web page from a website on the internet (Google). First we need to connect to the server that will be serving the page we require using…
Taking temperature readings with a microcontroller may seem confusing at first sight, especially if you’re new to Arduino. In this tutorial, we simplify this as much as possible. We will use an inexpensive LM35Dz temperature sensor, a few cables and an Uno. You will need: LM35DZ Temperature Sensor 3 x Male to female Cables An Arduino development…
