In this example we will connect a HDC1000 sensor to a data logging shield and log out the temperature and humidity to a csv file on an SD card Here is…
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.…
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…
This was another example of driving an 8×8 LED matrix , this time we decided to use Johnny-five (http://johnny-five.io/) , we were having a play about with Javascript. The process…
In this example we will show the temperature and humidity readings from a HDC100x series sensor and display this on a 16×2 LCD. First lets take a look at the…
In this example we will program an Attiny44 using an Arduino The first step is to take a look at the pinouts and features available if you decide to use…
In this part we will now try and program an Attiny85 microcontroller using an Arduino, the process is similar to our Attiny2313 example. Basically slightly different connections and change the…
