Step 1: Read a sensor value or potentiometer value
run this to receive singles bytes of a sensor value. Receive the bytes using processing, puredata or other software.
int analogValue;
void setup () {
Serial.begin(9600);
}
void loop () {
analogValue = analogRead(A0)/4;
Serial.write((char)analogValue); // char is a byte
delay(100);
}
Step 2: Read multiple sensor values
Problems + Solutions - discussion in class.
Homework:
1. Get Arduino running with one or more sensors and write a small test sketch in processing (or a program in your favourite language) to receive the two values.
2. Build a sensor of conductive material and experiment with it. Find an application using it. Document your Experiments in drawings, videos, photos.
