Arduino

This is the fifth post in my little “Out of Boredom” series dedicated to hobby projects with Arduino. Previous posts were all .NET based:

Time for the third episode of “Out of Boredom” series :) There was a Sonar project and something about shooting paintballs… This time you will learn how to use Arduino and .NET 4.5 to receive input from joystick and use it to control servos that move a webcam horizontally and vertically!

My first Arduino based project was Sonar with C#, JS and HTML5. Now I continue the “Out of Boredom” series with a setup that allows firing a paintball marker (gun) with a command sent from a computer :) This time software stack is simpler - just a small Arduino sketch and uncomplicated WinForms (.NET/C#) application, but hardware requires a bit of electronics knowledge. Don’t worry though, nothing too complicated - I’m definitely not an expert in this field…

Part 1 described the general idea behind Sonar project, hardware components used and Arduino sketch… This second post in “Out of Boredom” series is about C# and JavaScript programs that make it possible to display ultrasonic range sensor data in web browsers. The role of .NET application is to receive messages from Arduino over serial port and broadcast it to clients using SignalR library. JS/HTML5 clients use jquery.signalR lib to obtain information about servo position with distance to obstacles and use this data to render sonar image on canvas:

This post marks the beginning of “Out of Boredom” series. It will be about creating stuff with my recently purchased Arduino Uno. Let’s have a break from chores of professional programming and create something just for fun :)
