Polled LED

Arduino code block for LED voltage analysis.¶

The .ino exercise can be downloaded here. The code will compile and execute in the Arduino Serial Monitor, but it is meant to be completed, following the LED Lab Instructions

// Polled LED.  Make LED turn on and off based on keyboard input.  
// On-off achieved by giving 5V to the circuit with a digital ouput.
// One solution is to change the LED circuit state every time you see a keystroke.
// Another solution is to read the keyboard input and have the LED change state based
// on specific keyboard input.

// Initialize variables to store the pin number and the keyboard input.


void setup() {

    // Initiate communication with the serial monitor.
    Serial.begin(9600);     // opens serial port, sets data rate to 9600 bps

    // Set the state of your digital pin to output.

}

void loop() {

        // Monitor the serial connection.  If it is open, read from serial port
        // If the On-off Pin is high, set it to low.  Otherwise, set it to high.
        // This will guarantee that the pin always changes state.

        if (Serial.available() > 0) {
                // read the incoming byte:

               }
