In this example we will add bluetooth support to our Arduino, there are several low cost modules labelled either Hc-05 or HC-06. Here is a picture of one of them In this example we will connect one of these modules …

I  decided to use Johnny-five (http://johnny-five.io/) , we were having a play about with Javascript. In this example I wanted see how easy it was to write something on an LCD, to be eact I would be using an LCD keypad …

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 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 …

This is a simple data logging shield which will enable you to add SDCard storage support and RTC capability to your Arduino project. Here is a picture of the shield that I purchased Features Here is a summary of the …

The PCF8574 is an 8 bits I/O port expander that uses the I2C protocol. Using this IC, you can use only the SDA and SCL pins of your Arduino board to control up to 8 digital I/O ports. This 8-bit …

In this example we use the DHT22 (or AM2302) humidity/temperature sensor and the Arduino UNO board to read data and print it out to the serial monitor. The DHT22 is better than the DHT11 because it has a wider range of …

I fancied trying the https://www.arduino.cc/en/Tutorial/CapacitanceMeter , to look at the theory visit that page. I was wanting to see how accurate this is and also wanted to test this on other variants such as the Chipkit and the MSP_EXP430G2 to …
