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.

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

The easiest way to measure a resistive sensor is to connect one end to power and the other to a pull-down resistor to ground. Then the point between the fixed pull down resistor and the variable FSR ...

Servo motors and are constructed out of basic DC motors, by adding: • gear reduction • a position sensor for the motor shaft • an electronic circuit that controls the motor's operation Typically, a ...

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 ...
