Tetrix PRIZM Tutorial 2 – Hello World

Alright, it is time to do some fun programming with PRIZM. The obligatory first challenge has to be HELLO WORLD. This is just standard programming protocol when starting any new learning with a device.

For this activity you will need

1. PRIZM
2. USB cable to connect to computer
3. Arduino software
4. Battery supply
5. On/Off switch

If you have not already downloaded the PRIZM library, then please do so as we will be using the example code provided for this challenge.

Step 1: Your first step is to open up the first sketch in the library called Blink_RedLED

You should see the following code

/* PRIZM Controller example program
* Blink the PRIZM red LED at a 1 second flash rate
* author PWU on 08/05/2016
*/

#include <PRIZM.h> // include the PRIZM library

PRIZM prizm; // instantiate a PRIZM object “prizm” so we can use its functions

void setup() {

prizm.PrizmBegin(); // initialize the PRIZM controller

}

void loop() { // repeat this code in a loop

prizm.setGreenLED(HIGH); // turn the RED LED on
delay(1000); // wait here for 1000ms (1 second)
prizm.setGreenLED(LOW); // turn the RED LED off
delay(1000); // wait here for 1000ms (1 second)

}

Step 2: Go ahead on turn on the power to the PRIZM. We need to make sure the device is recognized by the computer and ready to rock and roll.

Step 3: Verify the code.It should be good since it is in the library, but it is a good habit to practice when you start writing your own code.

Step 4: Upload the sketch to PRIZM. Once the orange light stops blinking on the PRIZM you are good.

Step 5: Push the green start button

BOOM! You should see your red light flash off and on.

What next?

1. Can you turn on the green light?
2. Can you mix and match the red and green?
3. Can you change the tempo of the lights?
4. Can you create a pattern on morse code?
