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…
How to get started with our serial seven segment display module and make a cool scrolling display. This 8 Digit Seven Segment Display Module takes advantage of the Maxim MAX7219 driver IC to allow you to driver its 8 seven segment LED’s using just 3 digital pins. The display removes all the awkward things…
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…
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…
Building your own hardware is always fun, especially when it’s combined with the Arduino platform. For this product a combination of the two are used to create something that’s both fun and useful. The Sketch Pad is a kit of parts which includes a custom PCB that when soldered together creates an Arduino compatible development board including the…
Items you will need: Arduino development board such as this one Male to female dupont cables Colour sensor module What does it do? This sketch will read the output of the sensor in the four different colour modes (red, green, blue, and clear) and output the readings as a value between 0 and 255 to the…
Items you will need: Arduino development board such as this one Male to female dupont cables Rotary encoder module What does it do? This is basic example of how to read the state of a rotary encoder such as the KY040 Rotary Encoder Module (HCMODU0063). Pinout: 1…GND 2…+5V supply 3…SW connects pin to GND whebn…
Items you will need: Arduino development board such as this one Male to female dupont cables Passive Buzzer Module 100R Resistor Pinout: PIN 1: Speaker input (Connect this via a 100R resistor) PIN 2: NA PIN 3: GND What does it do? This is a very simple module that requires only one DIO pin (defined…
