This board have a built-in 4-digit 7-segment LED display and it requires a minimum of only one I/O line to control it. It is possible to control the display through two different communication interfaces: Serial TTL or I2C
The Easy Motor Controller allows to control the speed and the direction of rotation of a DC motor through three different possible inputs: analog (potentiometer), radio control RC, I2C digital communication.
Includes management of the limit switches
High performance IP54 Linear Actuator, the engine has a metal gearbox, a dynamic load rating of 50kg and a maximum speed of 1.5cm / s.
Two limit switches safely stop the motor at either end of its range.
The Relay Shield is an Arduino compatible module that provides an easy way to control high voltage thanks to 4 independent channels equipped with photo-coupled mechanical relays preassembled on the board. The maximum switching power is 1250VAac or 150Wdc
The Freescale MMA8451Q 3-axis accelerometer is a great low-g sensor with I2C digital port and adjustable sensitivity (±2g, ±4g or ±8g).
