Global Class

Local Classes

Our local class this week consisted of experimenting with multiple input devices:

We started with the above pictured simple circuit with a button and an LED.

Then, we moved onto a more complex version of it. We wanted to digitally read if the button was being pressed, so we hooked up the button to our Barduino:

So after we set the circuit up, we wrote the following code:

#define PIN 17

void setup () {
pinMode(PIN, INPUT);

Serial.begin(15200);
}

void loop () {
int reading = digitalRead(PIN);

Serial.println(reading);

delay(20);

}

Assignments

1. Probe an input device(s)'s analog levels and digital signals as a group.

The documentation of the work we did can be found here.

2. Measure something: add a sensor to a microcontroller board that you have designed and read it.
