I would like to introduce you to one of my interesting projects. It is a wireless thermometer that measures the indoor and outdoor temperature. The device consists of two parts. One is a transmitter that contains one digital temperature sensor and a transmitter module. A second receiver consisting of an LCD screen, the analog sensor […]

Description: The MS5637 is an ultra-compact micro altimeter. It is optimized for altimeter and barometer applications in Smart-phones and Tablet PCs. The altitude resolution at sea level is 13 cm of air. The sensor module includes a high-linearity pressure sensor and an ultra-low power 24 bit ΔΣ ADC with internal factory-calibrated coefficients. It provides a

Arduino is an open source prototyping platform for electronics. There is so much you can do with Arduino and the community is proof. In playing with Arduino I decided that it would be a great project to create a small multitasking library for use on AVR platforms, which includes Arduino. A small introduction avr-os is

I have been successful in programming my Arduino to identify sets of digits transmitted from my Samsung remote. I used the excellent library at http://www.arcfn.com/2009/08/multi-protocol-infrared-remote-library.html as a starting point. I stripped out everything that wasn’t a raw number, and started logging what numbers came across the serial monitor as I pressed buttons. I then created
