I have had some problems with my "lab power supply" and I wanted to build another one, so I thought a DC load may be handy to have around.
The design is based around Dave's simple DC load, but with a couple more features, including:

-Arduino controlled.
-Voltage, current, power and temperature monitoring.
-CC and external-in hardware modes and CP, Cr software modes.
-Over temperature, over power and over current protection (software)

It can handle around 4 amps and 24 volts, limited by the mosfet.

All the code can be found here: https://github.com/Juan-Gg/Arduino-Based-Electronic-Load

This project was featured in Hackaday (https://hackaday.com/2019/02/28/spot-this-diy-electronic-loads-gracefully-hidden-hacks/). Thank you for the feedback. And yes, I did spell "dynamic" wrong, fixed that thanks to MS Paint.
