The Accelerometer Block provides two analog signals corresponding to the acceleration the block is experiencing on the x-axis and the y-axis. This sensor can therefore act as a tilt sensor in two directions.

The block requires 5V power and a 0V connection from another source.

When perfectly flat the accelerometer is designed to output 2.5V. The exact value tends to vary from device to device, so a trimpot is provided for each axis to enable the user to center the output precisely at 2.5V.

Assuming the board is being held flat with respect to the ground, when it is tipped to the right (as it is illustrated above) the X axis output will read a higher value. When tipped to the left it will report a lower value. Similarly, the Y axis output will read higher when the board is tipped forward and lower when tipped back.

The outputs are relatively weak and can't supply much current - it is suggested that they only be used as inputs to devices that do not require much current. These can be connected to inputs on devices like the Poly Block, Servo Block, Stepper Block, Line Block, and Switch Block.
