DIY - Speedometer using Arduino and Processing

Hi, I just made a video that explains how to make a speedometer using Arduino and Processing. The speed is measured with help of a hall sensor. It can be displayed through processing either on PC (JAVA-Serial com.)  or on mobile phone (ANDROID-Bluetooth). However this video will just give a glimpse on how to get started.

Let me know if u need any help.

Happy learning!!
