[Boris Landoni] put together a guide to using an inexpensive 3-axis accelerometer with Arduino. The chip that he chose for the exercise is an MMA7455L made by Freescale. It’s got a lot of nic… ...

Essentially, it is another safety initiative that gives a visual warning of a biker braking, with LEDs tucking up the end of the handlebars. It is based on an 3-axis accelerometer board, provided by ...

One feature I don’t see implemented is a open/closed hand sensor. Could be as simple as a button on the palm, but it would add yet another layer of glove-like control to the thing. Of course ...

So I found out there was a sensor board (commonly named GY-87) which had three sensors on it: HMC5883L (compass), BMP085 (pressure, altitude, temperature) and MPU6050 (accelerometer and gyroscope).

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Electronica: Bio-potential sensor and 3D accelerometer in one chip for wearables STMicroelectronics is aiming at healthcare wearables with an IC that senses bio-potentials and acceleration, and ...
