Control everything with a DAC, and you have a programmable load controlled by an Arduino. With such a small form factor, getting rid of all that heat was bound to be a problem.

If you ever wanted to adjust a circuit using a digital version of a potentiometer (variable resistor) controlled by an Arduino then this is the easy way to do it - and at a price that won't break the ...

The AD5273 64-step digital trimmer offers a one-time-programmable (OTP) digitally controlled variable resistor (VR) that performs the same electronic adjustment function as a variable resistor or ...

As explained by Arduino to Go, each color band on the resistor corresponds to a number but this can differ depending on the band's placement.It's not complicated, but the sheer number of colors ...

The security flaws on this common hotel keycard lock are nothing short of face-palmingly stupid. Look closely at the picture above. This is a hotel room door swinging open. The device he holds in h… ...

This paper presents a novel Programmable Optically Variable Resistor (POVR) that provides a wide, continuously adjustable resistance range using an LED-LDR (Light Emitting Diode-Light Dependent ...

Programmable resistors to put hardware-in-the-loop Pickering Interfaces, has announced a family of one-slot PXI and PXIe programmable resistor modules that can handle 2A, 200V or 15W. Models 40-254 ...
