Voltage Bricklet¶

Features¶

• Measures voltages up to 50V (DC)

• Output in 1mV steps (12bit resolution)

Description¶

The Voltage Bricklet can be used to extend the features of Bricks by the capability to measure voltages. The measurement range is 0-50V (DC). The voltage can be read out directly in Volt without conversion. With configurable events it is possible to react on changing voltages without polling.

Test your Voltage Bricklet¶

To test a Voltage 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 Voltage Bricklet to a Brick with a Bricklet Cable. Additionally connect a voltage source to the Bricklet. For testing purposes we have connected a battery (see picture below).

If you connect the Brick to the PC over USB, you should see a new tab named "Voltage Bricklet" in the Brick Viewer after a moment. Select this tab. If everything went as expected you can now see the voltage in volt and a graph that shows the voltage over time.

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