but not sure that the heat released from MOSFET is over maximum heat the conductive thread can take.
... Each painted area changes its colour every time the Arduino applies heat to it...
While the max. current from an Arduino pin can be approx. 30-40mA (depending on resistor value) you can assume a power about 200mW
Hi,I've just received all part and quickly wired them like this:FET Gate --- 100? --- Arduino D5FET Drain --- Heating Element --- 12v +FET Source --- GndA picture is also attached.The problem i have so far is after providing full 5v to the FET Gate for a while, the heating element is not heated up. The part that is completely hot is the FET itself. Is there anything wrong in my wiring?
Can you clearly state what type of mosfet you are trying to use? The drawing says IRFZ44 which is not a LOGIC LEVEL mosfet and will not turn on fully with a arduino digital output. You have been told repeatably that you need to use a logic level mosfet.
?? What is the resistance of the heater??How much current do you expect to put through the heater??
