Importing custom artwork into a PCB CAD program is a fun way to personalize your board.
How to set up an Arduino as an in-system programmer (ISP) and program an Atmel ATtiny84A to blink
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.
Let's dissect another section of EdiBot 2.0 and learn how to spin DC motors with Python.
The newest version of EdiBot relies on contour finding in OpenCV to locate and chase yellow objects.
