Arduino Based Dual LED Desk Light Controller

This is the kind of DIY that as an arduino lover you not only enjoy making but which you like to out into use. About lights it is, but not flashy or showy. This is a robust, practical project, cheap to build, and one which is also a great learning experience.

The DIY started with the desire to build a switchless control for LEDs to radiate working space. Synaptics when used with arduino can give amazing results for the case. It works in two modes. In Relative mode it works like it works on a laptop – the mouse pointer will traverse from its present location in the direction of the finger. Since there are no mouse or laptop for this DIY, the Synapses will be used in the Absolute mode. The user should know the exact X/Y coordinates of where the fingers are going to move to and so the user can map areas to the monitor in the arduino Sketch. When movements are detected in those mapped areas, commands can be given and any number of tasks can be performed.

The design of the final project is no nonsense. There are no huge boxes to house the board. As for the sketch, its main purposes are to turn the Main LED on off, to manually control Main LED brightness, to set delayed time off, to on/off the secondary LED and to have the ability to save the Main LED brightness state.
