Motorized Linear Poti Bricklet

Features

  • Linear Potentiometer with 100mm fader travel
  • Fader position can be controlled by user and with a motor
  • No additional power supply necessary
  • Automatic calibration

Description

The Motorized Linear Poti Bricklet is equipped with a motor controllable 100mm linear potentiometer. It can be connected to a Brick.

The position of the potentiometer ranges from 0 (slider down) to 100 (slider up). A user can change the position of the potentiometer and it is possible to drive the potentiometer to any position with an integrated motor.

You can configure the potentiometer to hold the position. In this case it automatically drives back to the set-point when a user changes the position. If it is not configured to hold a position, the Bricklet will only drive to the set-point once and after that the user can control the position again.

The Motorized Linear Poti Bricklet has a 7 pole Bricklet connector and is connected to a Brick with a 7p-10p Bricklet cable.

Test your Motorized Linear Poti Bricklet

To test a Motorized Linear Poti Bricklet you need to have Brick Daemon and Brick Viewer installed. Brick Daemon acts as a proxy between the USB interface of the Bricks and the API bindings. Brick Viewer connects to Brick Daemon. It helps to figure out basic information about the connected Bricks and Bricklets and allows to test them.

Connect the Motorized Linear Poti Bricklet to a Brick with a Bricklet Cable.

If you connect the Brick to the PC over USB, you should see a new tab named "Motorized Linear Poti Bricklet" in the Brick Viewer after a moment. Select this tab. If everything went as expected you can now control the position of the potentiometer with the GUI.

After this test you can go on with writing your own application. See the Programming Interface section for the API of the Motorized Linear Poti Bricklet and examples in different programming languages.

Case

A laser-cut case for the Motorized Linear Poti Bricklet is available.

Case for Motorized Linear Poti Bricklet

The assembly is easiest if you follow the following steps:

  • Screw 12mm screws to bottom plate with nut,
  • screw Bricklet on 12mm screws with another nut,
  • attach the two small plates from the backside of the Bricklet to the bottom plate,
  • attach one of the side plates,
  • attach small plate from the frontside of the Bricklet to the side plate,
  • screw 12mm and 10mm spacer to small plates at both sides,
  • attach left and right plate,
  • attach other side plate and
  • attach top plate and screw it to spacers.
