9-in-1 Educational Shield for the Arduino UNO

For Arduino Uno and Compatibles

You can use the 9-in-1 Multifunction Shield for a variety of Arduino projects. The Shield is suitable for both beginner and experienced users on the Arduino platform. It can help you understand the basic concepts of different sensors, LEDs, Buzzers, Serial and I2C communications, switches and more! All you must do is plug the shield on to the top of your Arduino UNO and create or upload the corresponding code.

With this shield, you can learn how to read humidity and temperature, receive infrared signal from standard remote controllers, read light intensity, control single color or RGB LEDs, read input from switches, produce sounds through the onboard piezo speaker or read values from a variable potentiometer.

The Shield Contains

DHT11 Temperature and Humidity Sensor: Connected to Arduino Digital Pin 4
Piezo Buzzer: Connected to Arduino Digital Pin 5
Photoresistor (LDR) Light Sensitive Resistor: Connected to Arduino Analog Pin 1
LM35 Temperature Sensor: Connected to Arduino Analog Pin 2
Three-color RGB LED: Connected to Arduino Digital Pins 9, 10 and 11
Push Button Switches (SW1 and SW2): Connected to Arduino Digital Pin 2 and 3
Red and Blue LEDs (LED1 and LED2): Connected to Arduino Digital Pin 13 and 12
Infrared Receiver Sensor: Connected to Arduino Digital Pin 6
Rotary Potentiometer: Connected to Arduino Analog Pin 0

Example - Temperature Sensor on Analog A2

/* PCBoard.ca - Embedded Temperature Sensor LM35

  9-in-1 Educational Shield Read temperature from LM35 sensor on analog port A2

  and display value on Serial Monitor at 9600 baud every second.

  --> Don't forget to enable the Serial Monitor at 9600 baud to see the output!

*/



const int lm35_pin = A2; /* LM35 O/P pin */

void setup() {

  Serial.begin(9600);

}

void loop() {

  int temp_adc_val;

  float temp_val;

  temp_adc_val = analogRead(lm35_pin); /* Read Temperature */

  temp_val = (temp_adc_val * 4.88); /* Convert adc value to equivalent voltage */

  temp_val = (temp_val/10); /* LM35 gives output of 10mv/°C */

  Serial.print("Temperature is ");

  Serial.print(temp_val);

  Serial.print(" Degree Celsius\n");

  delay(1000); /* Pause for 100mS (1 second) */

}

Example - Switch Press On D3, Toggle LEDs On D12 and D13

/* PCBoard.ca - Embedded Swith and LED

  9-in-1 Educational Shield

  Watch for button presses on switch SW2 and alternate LED1/LED2 on button press */
