# ERSTE SCHRITTE: DAS 5X5 LED RASTER ## Introduction @unplugged The Calliope mini is equipped with a number of sensors: It has a temperature sensor, a light sensor, a compass as well as a microphone. ## Step 1 @fullscreen ### Displaying sensor data In order to display data from your sensors on the Calliope mini’s LED matrix, you need to select a sensor (value). To do so go to the Basic section and select the "show number 0“ block. Within the number you can now change the "0“ to the value of a sensor. ## Step 2 @fullscreen ### Acceleration sensor You can select the acceleration values by dragging the block from the Input section and place it on top of the "0“ (which will disappear). ## Step 3 @fullscreen ### Light sensor The light is measured by the LED matrix. You can select the light sensor by dragging the block from the Input section into the number block. ## Step 4 @fullscreen ### Compass The built in magnetometer allows the Calliope mini to tell in which direction it is facing. This sensor will provide a value between 0 and 360 degrees. The compass will need to be calibrated before use. Follow the instructions on the Calliope mini and tilt it in a circular fashion to display a complete circle. You can start using it by dragging the block from the Input section into the number block. ## Step 4 @fullscreen ### Temperature sensor You can select the temperature sensor by dragging the block from the Input section into the number block.
