Testing the ability to pulse the hot wire on and off via a potentiometer (dial).
In this circuit the heated wire has been substituted for a bulb to allow for an easier visual test.
In the video, the PWM (pulse width modulation) signal is sent via an oscilloscope. As can be seen, the signal being sent is flat on or flat off. This is the same signal I need to send from my Arduino. It is important this signal is precisely square or flat, as opposed to slightly curved because unwanted heat will be generated from the mosfet.
Also the rate at which the hot wire will pulse will also be changed. I just need to relate the dial's value (0-1023) to the amount of time the wire will be delayed on and off. This relation all depends on how hot the wire gets, so I will play around with this once the other components have been implemented.
