2. what IS ARDUINO Microcontroller Allows for quick prototyping of ideas
Accepts both digital and analog signals
Simple to use
Readily available online support / help / documentation
Big part of the QSET Rover

3. Downloading Arduino ide
Go to
Select “Download”
Download the appropriate version & follow instructions

4. Getting started Ensure Arduino.exe will open
Navigate to
Create an account
Then select “New Breadboard Circuit”

5. The breadboard Two sections Connected horizontally labelled by + and –
Each row is a separate piece of wire
Connected vertically labeled 1 – 60 in this case but can have more or less
Each column is a separate piece of wire
Pattern repeats after the dotted line. This gap separates the electrical connections.

6. Basic l.e.d. circuit The arrow marks the direction of current flow.
Voltage supply comes directly from the Arduino board (in this example)
V = 5 V
R = 330 Ω

7. Creating the circuit on 123d.circuits
DEMO

8. Writing the Arduino code
Typically in 3 main parts
Initialization of variables
Setting up the hardware to recognize components
Loop instance that runs indefinitely

9. 1. Initialization of variables
In this case we only need one variable
“int” denotes that it is an integer
led was the chosen name for the variable
13 is the pin we are plugging the LED into

10. 2. Setting up the hardware to recognize components
“Void setup() {“ tells the compiler we are going to start our setup phase of code
“pinMode” tells the compiler that we need to do a pin assignment. This instruction has the form: pinMode(PIN#,mode);
PIN# - Taken from the #s on the board
Mode – Tell the compiler if it is going to be an INPUT or an OUTPUT.
“}” denotes the end of the setup function

11. 3. Loop instance that runs indefinitely
“Void loop() {“ tells the compiler we are going to start our loop phase of code
“digitalWrite” tells the compiler that we would like to set a digital value. 1(current) OR 0(no current).
This instruction is of the form digitalWrite(PIN#, Value).
PIN# - The pin we want to alter
Value – Whether we want it to be a HIGH(1) or LOW(0)
“delay” tells the compiler to wait for a duration of 1000ms (1 second).

12. 3. Loop instance that runs indefinitely cont.
Now we do the “digitalWrite” to tell the LED to turn off and wait 1000ms
“}” tells the compiler that this is the end of the instructions that we want to loop
Once the program has executed the second delay, it will go up to the beginning of the loop and turn the LED on again

13. Now execute on 123d.ciruits
