The pibrella is a nice little board that connects yo the GPIO connector of your Raspberry PI. It has the folllowing to play around with Red, Green and yellow LEDs A push button switch A buzzer 4 inputs and 4 outputs (protected) I2C connector (not …

In a previous example we created a simple console program, in this example we will create a basic GUI program. To do this we need to install GTK. Lets begin by installing GTK for mono [codesyntax lang=”bash”] sudo apt-get install gtk-sharp2 [/codesyntax] Create a folder …

Previously we showed you a C# example for your Raspberry Pi. We installed a text editor and then the mono development environment. We then created our c sharp example in our text editor , compiled and ran it. This typically is the way you write …

Before I start I will say that this isn’t going to be some petty post that spends lots of time justifying and then putting down other programming languages. I’ve used C# and many other languages and I personally have no real favourites. In this example …

Raspberry PI A+, B+ and 2B GPIO J8 40-pin pinout. Raspberry PI Models A and B have only the first 26 pins. GPIO# 2nd func pin# pin# 2nd func GPIO# – +3V3 1 2 +5V – GPIO2 SDA1 (I2C) 3 4 +5V – GPIO3 SCL1 …

File and directory command line Directories List directory: ls List directory (wildcard matching): ls *.txt List all files of type: find . -name “*.txt” -print Switch/toggle between dirs: cd – Make empty directory: mkdir sample-directory Remove empty directory: rmdir sample-directory Remove directory with all contents: …

In this example we will connect a capacitive sensor to a GPIO pin on our Raspberry PI, when we touch the sensor we will display a message to the user. A practical use may be a touch activated lamp. This is the sensor we used …

Flash the ACT led from the command line, this tip was sent to me so I gave it a try, you could this in a script. The LED in question is seen below, this may depend on the version of Raspberry PI you have as …

Here are a couple of BASH scripts to display the temperature of the BCM2835 SoC used on the Raspberry PI. Using this its fairly simple to create a temperature logging system or even going a step further and if the temperature exceeded a maximum you …

Raspberry Pi hardware information, open up the terminal and type the commands listed below, you can also see the output from the terminal cat /proc/cpuinfo displays details about the device’s processor. cat /proc/meminfo displays details about the Raspberry Pi’s memory cat /proc/partitions reveals the size …
