It’s a 360 degree multifunctional programmable sensor that has a bundle of cool features for sensing for your Maker, Robot and Kinetic art type projects.
The sensors is also packed with two ambient light sensors (for light tracking experiments or line following) and IR remote control functionality so it can can read and transmit Sony SIRC IR control signals.
Infrared Control Freak 360 – ROBOTmaker
The sensor is designed to fit onto micro sized robots (50mm x 50mm) where 360 degrees of proximity sensing, ambient light sensing and basic inter-robot communication is required, such as robot swarms, robot research, robot gaming and robot sumo competitions.
This project, called “Simple-Timer” is a programmable Timer and electronic switch with an integrated LiPo Battery Monitor that is based around a PIC microcontroller.
The “Simple-Timer” includes a fairly accurate timer that is programmable (via pushbutton) by the user and can be programmed to time a 5, 10, 15, 20,25 or 30 minute event. When the timer/switch is enabled (tap small pushbutton), the onboard LED indicates the output is active by lighting solid (the circuit also outputs the same voltage as your supply/battery voltage using a PN2222 NPN transistor or a high current MOSFET).
An accelerometer is a device that measures non-gravitational accelerations. These are accelerations produced by mechanically accelerating the accelerometer via its casing. – Accelerometer Wikipedia
Sci-Spot.com – Accelerometer – An accelerometer is a device which measures acceleration; how fast it’s speeding up. In the past an accelerometer could be a complex, bulky piece of equipment, but in
today’s world, accelerometers are available as single ic’s and use complex microscale machining technology.
MMA7260Q is a 3-axis accelerometer from Freescale Semiconductor. This accelerometer can be used with an extension Library Mma7260q which simplifies some initialization values and tilt detection.
ADXL105 Lower-Noise Wider-Bandwidth Accelerometer – The ADXL105, a near-ideal kind of vibration sensor, eliminates significant problems with existing vibration sensors, such as piezoelectric and bulk capacitive sensors. Primary benefits derive from much lower cost, stable sensitivity as a function of frequency and temperature, ruggedness, and ease of use. Besides machine health and condition monitoring, it is particularly well suited for noise and vibration cancellation applications.
