Motors provide a clean way to convert electrical energy (such as from batteries) into mechanical energy (or movement.) This document explains what a motor is, a little of the theory about how it works, and shows some of the different types of motors.
Radio Control (RC) Servos are a simple way to provide electronically controlled movement for many projects. It does not refer to the more general, wide-ranging, description of a servo motor – that is a motor which has feedback control.
A guide to understanding how a Potential Divider / Voltage Divider works. What is a Potential Divider / Voltage Divider? This is a simple circuit which takes advantage of the way voltages drop across resistors in series.
Have you ever made a mistake soldering? Heard of solder wick but not sure how to use it? Or perhaps you've seen a solder sucker but not sure if it's the right tool for the job. Join Kevin as he shows you show to remove solder.
A guide to understanding how a thermistor works. A thermistor is a component that has a resistance that changes with temperature. There are two types of thermistor. Those with a resistance that increase with temperature (Positive Temperature Coefficient – PTC) and those with a resistance that falls with temperature (Negative Temperature Coefficient – NTC).
