He sourced a 10W power LED which requires 12V @950mA ... sensor to his Arduino in order to shut it down if it gets too hot. The Arduino also provides the dimming circuit and remote control ...

With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips”- for instance ... chip and insert it ...

Obviously, when the switch is opened, dimmer #4 goes to zero, then dimmer #3 ramps down to zero, then #2, and finally #1 circuit. Help please.” I only had the Arduino UNO board and a couple of LEDs so ...
