Sensors / Prototyping Board:

» Pr 01: Reading the ADC at Prototyping 2.0 Board

In this example we read the analog-to-digital converter of the Prototyping 2.0 board every second and print the value obtained through the USB port.

Required Materials

1 x Waspmote
1 x Battery
1 x Coin cell
1 x MiniUSB wire
1 x Prototyping 2.0 board

Notes

Take a look at the Prototyping 2.0 board technical guide for information about how to attach the sensor or device to be read to the analog-to-digital converter of the board.
