Arduino – Control a DC motor with TIP120, potentiometer and multiple power supplies

Metering – Instrument Projects, Motor Projects /

A simple diagram demonstrating how to regulate the velocity of a DC motor using a potentiometer connected to your Arduino device. Additionally demonstrates the method of utilizing a TIP120 transistor for enabling the Arduino to manage a more powerful power source. Transistors consist of 3 pins, with the third pin (Base) enabling control of the […]

Upright Laser Harp

Upright Laser Harp

Other Projects /

Laser harps are musical devices with laser beam “strings.” When the beam is blocked, a note is played by the instrument. Usually laser harps have the beams travel vertically in the shape of a fan or vertical lines. In this project, I built a laser harp with stacked laser beams that propagate horizontally. The beams

Analogue Sensors – Calculate the Nonlinearity Introduced by a Load or Pull Down Resistor

Electronics News Updates /

Have you ever had that terrible feeling that adding a load resistor or ‘pull down’ to your sensor is messing up all your analogue readings? Maybe you’re wondering why we’d want to spoil a perfectly good circuit by putting in a load resistor at all? For many years I found that I would get strange,

Building a DIY Digital Voltmeter with Arduino: A Beginner’s Guide

Development Board – Kits Projects /

Creating a straightforward digital voltmeter with an Arduino and a 16×2 liquid crystal display (LCD) is a straightforward process. Measuring voltages with an Arduino is relatively uncomplicated. The Arduino provides multiple analog input pins that link to an internal analog-to-digital converter (ADC). The Arduino ADC, which is a ten-bit converter, produces output values ranging from
