As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it&#8… ...

Users will need to provide their own Arduino Pro Mini and the hardware features a 1.4 W, 8 Ohms, Texas Instruments TPA2005D1, 14 bit ganged PWM, PWM 8 kHz low pass smoothing filter all powered by ...

For parts, I needed three things: a sound sensor, a computer brain to run it and a place to store the data. The best-known tool of the open hardware movement is the Arduino, which costs about $30 ...

The blog post written by Michael Manoochehri who is a Developer Programs Engineer, outlined their plan to place hundreds of Arduino-based environmental sensors around the conference space to track ...

For one, the sound doesn’t directly control the solid state relay used in the fan controller. When the microphone equipped Arduino detects enough noise, it will start a timer that keeps the fan ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

Researchers at Duke University have developed a prototype sensor that’s not only able to figure out the direction of a particular sound, but can also extract it from background noise. The disk ...
