"Do you want to control your Arduino with an IR remote? Do you want to use your Arduino to control your stereo or other devices? This IR remote library lets you both send and receive IR remote codes in multiple protocols. It supports NEC, Sony SIRC, Philips RC5, Philips RC6, and raw protocols."

"My original plan for a final project, way back in week 1, was to build a internet-connected drum that counted politically sensitive numbers….However, after struggling for a week and a half…we gave up on Saturday night. [Instead we implemented] something akin to a VOIP over Internet Zero – the thinnest, cheapest digital audio communication possible."

"Well, it’s elementary simple in theory, how to do sound localization based on phase difference of signals, that received by two spatially distant microphones. The Devil, as always, in details. I’ve not seen any such project created for arduino, and get curious if it’s possible at all."

This week in our PyroEDU Analog Electronics course, we dive into transistor amplifiers. Here’s a quick intro of what this PyroEDU lesson is all about:

When it comes to analog electronics, amplifiers are just as important as filters since they serve the purpose of amplifying filtered signals. In this lesson we will build a simple single transistor amplifier and see its effect on an AC sine wave input.

"Interestingly the resistance of the material decreases when bent, implying that the electrical connections are being broken in the material because it is being stretched or damaged. When pressured the resistance through the material decreases."

"I have decided to create and document the design of a simple PID velocity DC motor controller. While this idea is not new or novel I feel that many people can take what I have learned from this project and implement it into their own designs."

"ArduCopter is an easy to set up and easy to fly platform for multirotors and helicopters. Its features go far beyond the basic manual control RC multicopters on the market today."

"This post shows how you can output VGA signals to a monitor, turning your Uno (or similar) processor into a ‘video card’."

This project is very similar to our own Arduino VGA output but much more comprehensive — including assembly code!

"I have been searching for ideas of making a Quadcopter Arduino flight controller Adapter to sit my Arduino nano board and the GY80, also have some header pins for motors and receiver to make the cabling tidy. There are a lot of Arduino shields people have designed for the Quadcopter. I didn’t follow any of the designs. I actually didn’t follow any planned design and solder the parts on the veroboard as I go along."

Now for a really fun lesson in our PyroEDU’s Analog Electronics course! This week we dive into Active filter circuits. Here’s a quick intro of what this PyroEDU lesson is all about:

This type of analog filter is one that utilizes op-amps which can make sure the input signal is the same strength as the output signal. In this lesson we will build an active band-pass filter and see the effect it has on an audio signal when we vary its parameters.
