The Grove 12 button Capacitive Touch Keypad is built around the ATtiny1616, an AVR® 8-bit processor running at up to 16 MHz. ATtiny1616 is a low-power, high-performance chip integrated QTouch® peripheral touch controller which supports capacitive touch interfaces with proximity sensing and driven shield. With this module, you can easily create an arduino password keypad or a DIY phone keypad.
GrovePi helps you build your own smart devices. The Base Kit includes the GrovePi board and 12 Grove sensors so you can build anything from a weather station or plant monitoring station to a MINECRAFT controller or automated rain notifier. Raspberry Pi sold separately.
Grove - 3-Axis Digital Accelerometer(±16g) (ADXL-345 ) also called 'Gyro'
Based on the excellent ADXL-345, this I2C digital 3-axis accelerometer has excellent EMI protection. Its variable output makes it suitable for a wide range of applications:
HDD shock protection
Vibration sensor
Game controller input
Robotics
Smart vehicles
Anywhere you need to obtain motion-sensing & orientation information.
