Lots of useful hardware and software projects suitable for beginners all the way up to the experienced user.
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…
Creating a simple connection between an LED and a light sensitive resistor. In this tutorial, I’ll use two inexpensive components (a LED and a Light Resistor) and create two circuits which will work together thanks to an Arduino. You will need: Breadboard LED LDR (Light Resistor) 5 x Jumper Cables 1 x 220ohm Resistor 1…
One of the most common uses for microcontrollers is for interfacing to various sensors to monitor the world around you. With an Arduino board you can read the value from a temperature sensor and output it to a computer in a matter of minutes. But what if your Arduino and sensor needs to be remotely…
Using an inexpensive component to play notes using your Arduino. In this tutorial we’ll be using a passive buzzer and an Arduino to play a series of notes. You will see that the sketch loops the main sketch so that the notes continue to run over and over (void loop). At the start of the…
Creating your own libraries can be time-consuming. We’ve created a library for various keypads and thought we’d share this, along with an example sketch to prove it works 😉 You will need: Matrix Keypad (for this example we’ll use a 4 x 4) 8 x Male to Male Cables Your Uno In order for…
Tutorial for illuminating and controlling LEDs. First things first – As with previous tutorials, we cannot stress enough that you must not connect an LED directly to the Uno. A resistor must be used to avoid damaging the LED and more importantly, your Arduino! For this tutorial, you will need the following: 1 x Breadboard…
