Please refer to the grade 11 course for information and details relating to Arduino.

PROGRAMS & CIRCUITS

Task #1 (Program only)

Write a program that will display HELLO WORLD to screen. Make sure you have selected the proper port in the Tools menu. Also, you will need to open the Serial Monitor tool.

Task #2 (Program only)

Write a program that will display HELLO WORLD to screen repeatedly. Include a delay between each display.

Task #3 (Program only)

Write a program that will display HELLO WORLD repeatedly along with the number of times that it has been displayed. You will make use of variables for this.

Task #4 (Circuit only)

Use an Arduino as the power source to light up an LED. No program is required to do this. See the sketch below.

Task #5 (Circuit & Program) <TEACHER VERIFIED>

Connect the circuit and write the program that will make an LED blink on and off.

In the sketch below, we have opted to use digital pin #5 to connect to the positive side of the LED. Using programming, we will have to make pin #5 alternate between a HIGH state and a LOW state to make the LED turn on and off.

Task #6 (Circuit & Program) <TEACHER VERIFIED>

Using a similar setup as above, connect the circuit and write the program that will make two LEDs blink. However, you must meet the following conditions:

· When one LED is on, the other is off.

· There is always one LED that is on and one that is off.

Task #7 (Circuit & Program) <TEACHER VERIFIED>

Still using a similar setup as above, connect the circuit and write the program that will make four LEDs each get their turn to be on for one second. This should repeat indefinitely. See the diagram below.

ABOUT BUTTONS

You will be given a push button. To know which sides are up/down and which are left/right, simply plug the button on a breadboard crossing over the ditch.

The left pins of the buttons are always connected together internally. Same goes for the right pins. When you press the button, a plate drops down connecting both the left side and the right side together.

Task #8 (Circuit only)

Create the following circuit that will simply make a button turn on/off an LED. The +5V and GND rails should be connected to the corresponding pins on the Arduino. No program required.

Task #9 (Circuit & Program)

Create the circuit and write the program that will check if a button is pressed or not. Every second, it should output either PRESSED or UNPRESSED depending on the state of the button.

Note that when doing a digitalRead on an Arduino’s pin, that pin needs to be connected to 0 or 1, not to an open circuit. A button switch, when unpressed, would be an open circuit. So, we have to use a pull-down resistor to avoid this. See the circuit sketch below to help you.

Task #10 (Circuit & Program)

Alter your program from above to count the number of times the button has been clicked. Output the total.

Task #11 (Circuit & Program)

You will use a button and an RGB LED. Everytime the button is pressed, it will change the mode of the LED and display a different colour.
