Ever wanted to create a way to control your garage door using your phone maybe collect data and view it from your laptop. There is a single board computer called the Beaglebone Black which is an extremely powerful device that allows you to control its GPIO pins in order to interact with real world items […]

Overview of Steps In the first phase, I will install only one LED. Next, I download the LED class python module that represent one hardware LED. I will run the LED class python module to blink that LED. The first phase serves as a “Proof of Concept”. In the second phase, I will install another
This project uses two groups of eight LEDs sharing eight GPIO pins via one of my Pi interfaces. The anodes of each group of LEDs are commoned and driven by a BFY51 transistor. The two transistors are controlled by a further two GPIO pins to select either one or the other group. To make things

Amy Ciavolino’s friends were stuck outside of her apartment waiting to be let in to the party. They repeatedly pressed Amy’s apartment buzzer with no luck. The buzzer was too quiet, and Amy’s party was too loud. Throughout the night, the cycle repeated: Amy’s friends pressed the buzzer, waited in vain, finally called Amy, and

I’ve always been interested in Charlieplexing, but never had any means to get into it. When I got my Raspberry Pi, I figured it would make a great platform to learn how to Charlieplex. There are already a ton of Instructables on Charlieplexing out there, so I won’t go into the theory behind it, or

I built this pretty simple 2x2x2 led cube for my raspberry pi, and wanted to share what i learnt. This is my first time using transistors so the circuit is probably not perfect, but it works as i intended it to. Here is what you will need to make one: – 1x raspberry pi –
