Arduino Multi-Mode Lamp with Soft Touch Switch

In another Arduino-based project of Instructables, a lamp is assembled with multiple light displays. And here the display is referred tocolor sequencer, dimming light, color chaser and firelight. These fascinating appearances can be chosen by a touch bar on the circuit board. The special feature of this lamp is that all the functions are developed in software, including the touch sensor.

The project is budget-friendly and therefore, minimal stuffs are required. The materials used here includesfilling the board with a microchip, the LEDs, a handful of resistors and some capacitorsalong with the necessary connecting hardware. They all are available at affordable rate.

The circuit for this project contains 3 RGB LEDs, a sort of common-anode Piranha type which holds three LEDs within its bodyand is available here. Each color is accompanied with a dropping resistor ad to be accurate, we need 220-ohm for green and blue and 330-ohm for Red. Further, a small LED can be added with a 1k-ohm as an indicator.

The IC used here is an ATMega-328 microchip. Further,a 16 MHz resonator for about 35c is also required. As we proceed, the Arduino system is used for the development and testing of the software and therefore a suitable ‘host’ is necessary. You can go for an Arduino ‘Nano’, a Boarduino and a RBBB board as they all are compatible.

Now, 2 x 16-pin sockets are used end-to-end as putting the microchip in a socket is a nice idea. And also the ATMel chip has only 28-pins soon the end, there will be some empty sockets.

The circuit as well as programming is tested through jumpers, which are connected to the ‘host’, an RBBB. This ensures that the wiring is rightly assembled before the Microchip is committed. Test it by running the program with the IC and then the resonator. This is followed by adding a 5v source and Presto and this must result in light.

After the circuit is completed, step into the ‘Sketching’, or programming. As the lamp loops through four different modes, it offers sequencing through all 4000 color combinations! But still there is room for a lot more features.
