I have a few examples of interfacing a PC to an Arduino over the com port, typically you use a program written in a language such as VB.net or C# and either send or recieve data back and forth. One …

In this example we fit the Digit shield to our Arduino Uno and then connect the HC-SR04 ultrasonic module as per the previous example You can read about the digit shield here   Requirements HC-SR04 Ultrasonic module Arduino Uno and USB cable …

This was a module that I bought called the SPI RGB 5V 4xSMD 5050 LED Light Module for Arduino. Sadly I could not find a great deal of information for it but eventually got it to work. Looking at the …

WS2812 family is a intelligent control LED light source that the control circuit and RGB chip are integrated in a package of 5050 components. It internal include intelligent digital port data latch and signal reshaping amplification drive circuit. effectively ensuring …

In previous posts we showed some examples for the 4067 16-Channel multiplexer – Arduino and 4067 LED example The HCF4051 device is a monolithic integrated circuit fabricated in MOS (metal oxide semiconductor) technology available in SO-16 and PDIP-16 packages. The HCF4051 analog …

In a previous example we used the 4067 to flash some LEDs – Arduino and 4067 LED example but you can also use the CD74HC4067 multiplexer / demultiplexer to read analog values from all 16 channels. This gives you the ability …

One of the fun things about Arduino’s is coming up with projects to use Arduino’s and various sensors or modules. In this project I was thinking about an example that would detect the presence of a person. In the world …

The 4067 was one of the IC’s that I wanted to connect up to various microcontrollers as it looke dextremely useful, here is a quick description from one of the datasheets with an overview of the functionality The HEF4067B is a …

In this example we will connect an XBox 360 (USB) joypad to a USB Host shield and flash some LEDs depending on what button was pressed on the joypad You will need a USB host shield, connect this to an Arduino UNO …

The ProtoSnap is an Arduino-compatible development platform aimed at teaching the basics of Arduino programming as efficiently as possible. It does not require any assembly, wiring, or soldering, so you can jump right into programming the ProtoSnap to control LEDs, buzzers, light …

A mercury tilt switch is a switch which opens and closes an electrical circuit when it is tilted at certain angles. When it is tilted a small amount of the liquid metal mercury makes contact with metal electrodes to close …

This shield uses a 4 digit, 7-segment display to give you the data you need. You can use it to make clocks, timers, show sensor data, or anything else you can dream up. Here is a picture of the shield …
