First of all LM385 operational amplifier shows more stable work when powered from 12V. Also it allows to use much bigger variety of N-channel MOSFET as a heat element with a gate voltage hight than 5V ...

We believe that [Jasper’s] Arduino based electronic load is one ... It is an especially great project for putting together your knowledge of MOSFET theory and opamp theory!

To drive a MOSFET requires more ... It’s a simple enough circuit, the threshold pin is pulled high so the output goes high, and the PWM drive from an Arduino is hooked up to the reset pin.

The arduino can also report relevant info like temperature, setpoint, MOSFET PWM, etc. which can be immediately ... the current Keep grounds common between the heater and thermistor circuits but keep ...

I currently deisgned a small circuit with an Arduino Uno to provide PWM and high/low side inputs ... The HO and LO are connected to the gate of the high and low side mosfets (IRF 1407 TO220), ...

The load on each Mosfet is a power distribution board with ... The difference between TLC59116 with Arduino GPIO is that TLC59116 do not have internal pull-high circuit. So that without pull-up ...
