Read analog data directly in Processing

This instructable presents a fast an easy way to use data received from an analog sensor in Processing. You will learn to utilize the Arduino and prototype electronic boards to read meaningful data from the environment. The sensors can be affected by the light, the orientation, or a user’s physical input. For this matter we will use photocell, accelerometer, and potentiometer.

Step 1 Preparation steps

1. Upload the “standardFirmata” example from the Arduino IDE in your Arduino board. If you are using Arduino UNO, there is a standard firmata for UNO.

2. Install Arduino library for processing in your libraries folder in the processing sketchbook
