Need 3A Touch Sensitive LED Dimmer circuit.LED voltage is 2.9-3.5,0.7-3A.? Answered

Input should not more then 12volts it is better if circuit works on 5volts,but ON/OFF and dimming will be touch based.

so, it's gonna need to be a conglomeration of 2 projects;

1, a high power led driver, dimmable by pwm (plenty on this site)
and
2, a touch controller that spits out pwm to the driver. (also plenty on this site).


You might not find both as one project, but it would be beating a dead horse to redesign it here in an answer.

Drivers

Example touch lamp

You would just need a connection between the arduino touch portion to go to the higher efficiency led driver (the example lamp is lower power than your light).
