Someone has been stealing my sandwiches. We'll use the two-way radio communication on the micro:bit to catch the thief.
For Part 3 of the "Getting started with micro:bit" series, we read temperature from a built-in sensor and rotate a servo.
A set of calipers can be an incredibly useful tool for precisely measuring the distance between objects.
Staring at the multitude of buttons, switches and knobs on the face of an oscilloscope can be daunting. For this "Adventures in Science," we show you how to take basic measurements with an oscilloscope.
Looking to upgrade your workshop or mad science lab with more power? Here's how to get started with benchtop power supplies.
Just getting into electronics or want a refresher on digital multimeter basics? We've got you covered.
There are two basic ways to connect electronic components with two terminals: series and parallel. In this episode, we examine those two types of circuits and show how to calculate equivalent resistance.
Power is the rate of doing work, and for electricity, that means the rate in which energy is converted in a circuit.
Let's look at the resistor and how it affects current and voltage in a circuit. Here's a hint: if you know two of either voltage, current or resistance, you can solve for the third.
Over the next few weeks, we'll explore the basics behind electricity in a series of videos.
