"We are often asked on discussion boards, about conflicts between IRremote or IRLib and other Arduino Libraries. In this post, we present a sketch for ‘Simple Infrared PWM on Arduino’. This is the first part in a 3 part series of posts"

This week we are learning how to detect sound in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about Sound Sensors and perform a fun experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

We all hear and use sound in our daily lives, so we must also learn how to detect sound electronically. In this lesson we will use an electret microphone to convert sound from an acoustic wave, into an electrical signal.

"Holding the button in is a kind of ‘diagnostics’ mode which shows more information. Under normal operation it simply shows the vacuum pressure."

"The solder matters, it is an undisputable fact confirmed daily in a development and production of electronics. Hand soldering of prototypes, automated machine soldering, soldering of small SMT components or on the in contrast soldering of big joints of massive connectors, rework, all that wants a solder optimized for a given usage."

"If you are a beginner to Raspberry Pi and were looking for a simple hardware project, then look no further. This tutorial will show you to develop a python based robot which avoids obstacles and navigates freely. Obstacle avoiding robots are fairly common and easy to make."

"During World War I and slightly before World War II, military fighter aircraft had machine guns mounted to fuselage of the plane. These machine guns were mounted right behind the propeller. The first question that comes to mind is how can the gun fire and not hit the propeller blades as they are spinning? Some planes had special steel plates mounted to the propeller to keep the bullets from shredding the propeller."

Today we are learning about infrared encoder sensors in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about Infrared Encoders and perform a fun experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

Detecting changes in color and reflectivity can be achieved using an infrared emitter and phototransistor. In this lesson we’ll do just that by making a rotary encoder for tracking a motor’s movement.

"The device runs in both host and peripheral USB modes however in this design only the host connection has been used since i already had a peripheral interface breakout board already and therefore didn’t need this capability."

"The sound card runs at a sample rate of 48KHz, 32KHz or 24KHz selectable by the OS with 12 bits per sample. The quality approaches commercial grade as the sample rate is higher then CDs. 44.1KHz was not implemented due to the difficultly and additional processing overhead."

"I imagine you’re here because you have heard about the internet enabled fishtank, the world’s most advanced taking aquarium. I made it as a one-off project purely to push my technical skills to the limit and create something awesome."
