This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

LED Blinking: We use an LED (Light Emitting Diode), which is connected to the Arduino via a resistor. The resistor limits the current that flows through the LED to prevent it from burning by too much ...

This is a simple Arduino project that uses a force sensor and an LCD screen to display the amount of force applied to the sensor. The project is designed to help beginners get started with Arduino and ...

Potentiometers, or variable resistors, are a standard component that we take for granted. If it says “10k log” on a volume pot, than we fit and forget. But if like [Ben Holmes] you are modelling ...

Abstract: This paper describes a memristor emulator made up of an arduino-controlled digital potentiometer (DigPot) implementing the mathematical equations governing the HP memristor model. The ...
