Tips on setting up the MEGA 2560 board if you are having problems: Install the driver located at http://www.arduined.eu/ch340g-converter-windows-7-driver-download/ for windows. Or http://kiguino.moos.io/2014/12/31/how-to-use-arduino-nano-mini-pro-with-CH340G-on-mac-osx-yosemite.html for mac. If your PC is still having issues detecting the board, try this:

Download this driver file from the links above (which you already did): There will be a compressed file with two folders in it (INSTALL and CH341SER). Once you connect the board, go to device manager under control panel. Click the arrow on ports and expand it. Click update driver software and select manual install. Browse for the CH341SER folder and select it. Click OK. In the Arduino IDE, please make sure you have the following set up: Tools->Board->Arduino Genuino MEGA/MEGA2560 Tools->Programmer->AVR ISP Tools->Port->COM4 (or what that is available)

Part/Module Introduction Introduction to the parts in the Kit. Photo, quick introduction, pin connections and basic

code to get it working. The main idea here is for you to test out all the parts in the kit. If

something is wrong, let us know and we can troubleshoot for you or send a replacement if

needed.

If you would like to copy and paste code, please download the PDF file. Otherwise

you could view it in the browser window.

IR Flame Sensor

The Flame sensor is useful for determining the status, distance, or intensity of a flame. Whether it be a

pilot light on a water heater or the intensity of a campfire.

How it works – the IR Diode converts a flame’s light into a voltage (much like a solar cell). This low

voltage is amplified by the comparator which also triggers the Digital pin after the flame reaches a

certain intensity set by the user (with the built in potentiometer).

Power – 5v or 3.3v

Signal Type –

Analog Read – Connecting the flame sensors analog pin to any analog pin on the Arduino is

useful for determining the exact distance or intensity of a flame.

Digital Read – Connecting the flame sensors digital pin to the Arduino to know when the

intensity has hit a certain point. Useful if running out of analog pins on the Arduino or just

wanting to know when a flame has occurred.

Data Type –

Analog Read – Integer (values 0-1023)

Digital – Boolean

Pros – Simple to use, repeatable, directional.

Cons – Limited distance, nonlinear output

Projects and Uses – Monitor a Pilot Light, Flame detection if a stove or furnace is on

Sound Sensor

We are testing the Sound Sensor with Digital Input by displaying the result on the serial monitor whena

sound is detected. When the sensor detects a sound, the serial monitor will print 1 and when there is no

sound, it will print 0.

Parts

Sound Sensor

3x Male-Female Jumper Wire

Mega 2560 Board

Pin Connections

VCC->5V on UNO

GND-> Ground on UNO

OUT-> Any Digital Pin (Pin 2 in this example)

RIAspire

Code

int SoundSensorPin = 2;

int SoundSensor;

void setup() {

Serial.begin(9600);

pinMode(SoundSensorPin, INPUT);

pinMode(13, OUTPUT);

}

void loop() {

SoundSensor = digitalRead(SoundSensorPin);

Serial.println(SoundSensor);

digitalWrite(13,SoundSensor);

delay(1); // delay in between reads for stability

RC 522 RFID Card System

We are going to test out the RFID Card System. You will need to solder some headers on the receiver.

How it works – RFID stands for Radio Frequency Identification.

Signal Type – Digital

Data Type – Boolean

Pros – repeatable, each card has unique ID, allow multiple users access to a system

Cons – Code requires library to use

Library

https://github.com/miguelbalboa/rfid

Parts

1x RFID Reader

1x Card

1x FOB Keychain

7x Male-Female Jumper Wires

1x Mega 2560 Arduino-Compatible Board

RIAspire

Card Reader Connection

3.3V – 3.3V

GND – GND

SDA – Digital Pin 53

SCK – Digital Pin 52

MOSI – Digital Pin 51

MISO – Digital Pin 50

RST – 5

Ignore IRQ Pin

Code

Directions for the code. Once you have connected the reader, upload this code. Open the serial monitor

and swipe your card/keychain. The serial monitor will say “access denied” and also print the UID tag.

This happens because it does not know the ID for the card you are scanning. The UID Card that was

printed on the serial monitor is the ID for the card you swiped. Now go into the code and insert that UID

where is says “PLACE UID HERE”, leaving the quotations in place. The system should recognize the card

you are using now.

RIAspire

#include <SPI.h>

#include <MFRC522.h>

#define SS_PIN 53

#define RST_PIN 5

MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance.

void setup()

{

Serial.begin(9600); // Initiate a serial communication

SPI.begin(); // Initiate SPI bus

mfrc522.PCD_Init(); // Initiate MFRC522

Serial.println("Place your card or FOB keychain on the card reader");

Serial.println();

}

// Look for new cards

if ( ! mfrc522.PICC_IsNewCardPresent())

}

// Select one of the cards

//Show UID on serial monitor

Serial.print("UID tag :");

for (byte i = 0; i < mfrc522.uid.size; i++)

{

Serial.print(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " ");

Serial.print(mfrc522.uid.uidByte[i], HEX);

content.concat(String(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " "));

}

Serial.println();

Serial.print("Message : ");

if (content.substring(1) == "PLACE CARD UID HERE")

//insert the UID of the card you swiped up here

5V Relay

Let’s test the relay out. All we are going to do is turn it on or off. When it’s on, the green LED on the

relay will light up. Code is the same as the blink example.

Parts Needed

Relay

3x Male-Female Jumper Wires

MEGA 2560 Board

Pin Connections

VCC – 5V

GND – Ground

In – Digital Pin 2 (or any digital pin)

RIAspire

Code

// the setup function runs once when you press reset or power the board

void setup() {

// initialize digital pin 2 as an output.

pinMode(2, OUTPUT);

}

// the loop function runs over and over again forever

void loop() {

digitalWrite(2, HIGH); // turn the relay on (HIGH is the voltage level)

delay(1000); // wait for a second

digitalWrite(2, LOW); // turn the relay off by making the voltage LOW

delay(1000); // wait for a second

}

Let’s start with the LEDs: Arduino Tutorial #1 - Digital Inputs and Outputs - Button & LED https://www.youtube.com/watch?v=YWY_Is0L7fE Note: We provide 220 ohms resistors for the LEDs and 10K ohm resistors for the buttons. Without a resistor, an LED would burn due to the access current going through the LED(resistors limit the amount of current that flows through a circuit). Now let’s us discover an RGB (Red Green Blue) LEDs https://www.youtube.com/watch?v=Q72DvmcCe4I 74HC595 shift register with LEDs https://www.youtube.com/watch?v=bqfPZXEuyuc 74HC595 shift register with 7 segment LEDs https://www.youtube.com/watch?v=cHA-fwiA4Qo IR Remote sensor with 7 segment LEDs https://www.youtube.com/watch?v=caMW1RRPOGE Note: the IR configuration is different from what we have. However they share the same ideas. You can find the link for the code under the video. Photo sensor/Photo resistor (Photo cell in the video) with LED https://www.youtube.com/watch?v=vfn02TZDl_Q Now we can try and play with the LED Matrix to do more cool stuff. https://www.youtube.com/watch?v=TOuKnOG8atk Servo https://www.youtube.com/watch?v=TmpGXfVRd2A Potentiometer with Servo https://www.youtube.com/watch?v=xWjkuYSQcoI Joystick https://www.youtube.com/watch?v=MlDi0vO9Evg Servo could also be controlled using the Joy stick analog input signal, just like the Potentiometer with Servo example above.
