Sensors

Sensors and relational operators

• In addition to the buttons, the ED1 board incorporates different sensors: light, temperature, tilt, etc.

• Given that these sensors give an analog value (that is, numerical) we will have to use relational blocks if we want to execute actions related to it.

• These blocks also return a true or false value, so they can be used with the conditional blocks we saw earlier.

Challenge 1: Show two different patterns on the screen by covering and uncovering the light sensor

Solution to challenge 1

Temperature sensor

• Another sensor integrated into the board is the temperature sensor.

• A very simple example that can be done is to add to the graph the value that the sensor gives us every X time (for example 1 second) to visualize it comfortably.

• We can even export the data in .csv format and open it with a spreadsheet program (MSOffice, LibreOffice, etc.)
