Week 8: Arduino Sensors

This week we experimented with Arduino. Using 3 sensors we had to activate 3 actuators. The 3 actuators we used were the servo, LED and buzzer, and the 3 sensors we used were Ultrasonic sensor, shock sensor and tilt sensor.

All circuitry are made through tinkerCAD. Moreover, citations are all given in the comments next to each section of the code. Lastly, all codes edited and written be us have “Edited/written by H.” as a comment next to each section.

Actuator Codes (Our Base)

Circuitry

Code

Ultrasonic Sensor

The ultrasonic sensor is one out of 3 sensors we used. If the sensor detects something or someone closer than 7cm it switches the buzzer on, lights a red LED and the sheikhabot stops moving, whereas when the object is moved, a green LED is lit and the sheikhabot starts moving.

Circuitry

Code

Tilt Sensor

The tilt sensor activates the actuators when the sensor is being titled 180 degrees, meaning it will not activate any of the actuators when it is tilted. The buzzer goes off, sheikhabot moves and the LED emits red light.

Codes

Shock Sensor

The shock sensor activates when the sensor is violently moved activating all 3 actuators : the buzzer makes noise, the led glows red then green and the sheikhabot moves.

So you just got an Arduino! They’re definitely a lot of fun, but what’s next? Where do you start? Well, to do anything useful with it, you’re going to need to upload some code to it. To do that, you’ll first need to install the Arduino IDE (Integrated Development En...

Why not eh? (Note the very fitting choice of book ;p)

The code is quite clunky but it looks like this:

// --------------------------------------------------------------------------- //This is a sketch which develops the NewPing with the range sensor and the arduino tone function for an 'air keyboard' in the key of C, starting with C4. //(code is reasonably long and clunky until I figure out how to simplify it!) //pitches.h includes a library for tuned frequencies for the tone generator

#include <NewPing.h> #include <pitches.h>

#define TRIGGER_PIN 8 // Arduino pin tied to trigger pin on the ultrasonic sensor. #define ECHO_PIN 7 // Arduino pin tied to echo pin on the ultrasonic sensor. #define MAX_DISTANCE 500 // Maximum distance we want to ping for (in centimeters). Maximum sensor distance is rated at 400-500cm.

NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); // NewPing setup of pins and maximum distance.

int note1 = NOTE_C4;

int note2 = NOTE_D4;

int note3 = NOTE_E4;

int note4 = NOTE_F4;

int note5 = NOTE_G4;

int note6 = NOTE_A4;

int note7 = NOTE_B4;

int note8 = NOTE_C5;

void setup() { Serial.begin(115200); }

void loop(){ { delay(50); // Wait 50ms between pings (about 20 pings/sec). 29ms should be the shortest delay between pings. Serial.print("Ping: "); Serial.print(sonar.ping_cm()); // Send ping, get distance in cm and print result (0 = outside set distance range) Serial.println("cm"); }

{ while ((sonar.ping_cm() >= 2) &&(sonar.ping_cm() <=5)){ tone (12, note1); Serial.println("C4 is being played"); //send message to serial monitor and play the note C4 via tone function } } delay(25); // mandatory delay to prevent glitching between pings { while ((sonar.ping_cm() > 5 ) &&(sonar.ping_cm() <= 10)){ tone (12, note2); Serial.println("D4 is being played"); // same as above, one tone up } } delay(25); // same as previous { while ((sonar.ping_cm() > 10) && (sonar.ping_cm() <= 15)){ tone (12, note3); Serial.println("E4 is being played"); // same as above, one tone up } } delay(25); // same as previous { while ((sonar.ping_cm() > 15) && (sonar.ping_cm() <=20)){ tone (12, note4); Serial.println("F4 is being played"); // same as above, one tone up } } delay(25); // same as previous { while ((sonar.ping_cm() > 20) && (sonar.ping_cm() <= 25)){ tone (12, note5); Serial.println("G4 is being played"); // same as above, one tone up } } delay(25); // same as previous { while ((sonar.ping_cm() > 25) && (sonar.ping_cm() <=30)){ tone (12, note6); Serial.println("A5 is being played"); // same as above, one tone up } } delay(25); // same as previous { while ((sonar.ping_cm() > 30) && (sonar.ping_cm() <= 35)){ tone (12, note7); Serial.println("B5 is being played"); // same as above, one tone up } } delay(25); // same as previous { while ((sonar.ping_cm() > 35) && (sonar.ping_cm() <= 40)){ tone (12, note8); Serial.println("C5 is being played"); // same as above, one tone up } } delay(25); // same as previous { if (sonar.ping_cm() > 40) // stops tones when readings are above stated number in brackets, otherwise they play continuously when object is moved away (This can probably be fixed in the future!) noTone(12); } }

THE FOLLOWING VIDEO DEPICTS THE PROCEDURES REQUIRED TO INTERFACE THE LED MATRIX WITH ARDUINO MEGA.

THE COMPONENTS THAT YOU REQUIRE ARE:

1. ARDUINO MEGA.

2. SHIFT REGISTER.

3. BREADBOARD.

4. LED MATRIX MODULE.

TO START WITH THE INTERFACING PROCEDURE:

1. CONNECT THE CIRCUIT AS SHOWN IN THE SCHEMATIC GIVEN IN THE VIDEO.

2. WRITE THE CODE AS WRITTEN IN THE VIDEO. UPLOAD THE CODE AND YOUR LED MATRIX IS READY TO DISPLAY THE MESSAGE THAT YOU WANT TO DISPLAY.

# IMPORTANT:

DO THE CONNECTIONS CORRECTLY ELSE THE RESULT WON’T COME OUT ACCURATELY.

Interfacing 1602 LCD With Arduino

Today, we are going to talk about a Display Device which we use to display input and outputs. It is a 16X2 LCD display.

Here, we will use and arduino mega board and interface an lcd with it.

The components required for the interfacing are as follows:

1. Arduino Mega.

2. 16X2 LCD Module.

3. 10 K Potentiometer.

4. Bread Board.

5. Connecting Wire.

6. USB Cable.

The steps to interface LCD are as follows:

1. Fix the LCD Module onto the Breadboard firmly.

2. Connect PIN1 of LCD with GND.

3. Connect PIN2 of LCD with VCC.

4. Connect PIN3 of LCD with Potentiometer. This is the contrast pin.

5. Connect PIN4 of LCD with PIN7 of Arduino.

6. Connect PIN5 of LCD with GND. This is the RW pin of LCD. This must be low for writing onto the LCD.

7. Connect PIN6 of LCD with PIN6 of Arduino. This is the Enable pin of LCD.

8. Now connect the D4-D7 Pins of LCD with PIN 5,4,3,2 of the Arduino. These are the Data pins of the LCD and it will Work on the 4 Bit mode.

9. Now, Connect PIN15 of LCD with VCC and PIN16 with GND. These are the pins of Backlight Led.

10. Now, Write the code as shown in the video and upload the Code.

Your interfacing of LCD With Arduino is complete.
