As all college students know, sleep is one of those things you throw out the window when you have lots of work to do. With that sleep deprivation, comes careless mistakes that could cost you in the long run whether that be missing and exam, or an important class. Many of us, as myself, rely on our cell phone to wake us up in the morning. Although this method of waking up does work, with our busy lives we sometimes forget to set an alarm. We also sometimes forget to turn our sound on, or we forget to charge our phone causing it to die and not sounding the alarm. Even if you think that you will never make any mistakes setting your alarm, why take the second chance? Lots of times when pulling that long night of studying, an alarm just isn’t enough to wake you up. This alarm system will wake you up every time guaranteed with the implemented automated lights and sound, and this is how it works.
How it Works
There is a clock with a displayed time on the wall, as well as two servo motors. One servo controlling the lights, and another controlling the alarm. A desired wake up time is chosen, and once that time is reached, a particle photon controlling the clock signals the photon controlling one of the servo motors to turn of the light, and the other photon controlling the other servo to ring the “gong” setup in the room as the alarm. Once this is done the servos are sent back to the original position, ready for the next morning. The google sheet below shows the data of this process. When the time is reached the clock photon sends a variable which for graphing purposes is represented by a value of "1" to the other two photons receive the variable and start the process.
This is the code for our servo motor that turns the lights on
Servo myservo; // create servo object to control a servo
int pos=0; // variable to store the servo position
void setup(){ Particle.subscribe("alarm1234",servo); myservo.attach(D0); // attach the servo on the D0 pin to the servo object
myservo.write(45); // set the servo to 45°
pinMode(D7, OUTPUT); // set D7 as an output so we can flash the onboard LED
Spark.function("servo", updateServo);}int updateServo(String command){ uint8_t pos= command.toInt(); // convert string to integer
}void servo(const char *event, const char *data) // be accompanied by a string.
{if(strcmp(data,"Toggle")==0) // if the string is "Toggle", turn on the lights.
{ myservo.write(110); // move servo to 110 to flip the switch
digitalWrite(D7, HIGH); // flash the LED (as an indicator) delay(50); // wait50 ms
digitalWrite(D7, LOW); // turn off LED
}elseif((strcmp(data,"Off")==0)){ myservo.write(45); // when the alarm sends out the "Off" signal it will reset the servo to its resting position
}}
Alarm
Arduino
This is the code for the servo motor that rings the bell when the clock reaches desired time
Servo myservo; // create servo object to control a servo
int pos=0; // variable to store the servo position
void setup(){ Particle.subscribe("alarm1234",servo); // looks for what the alarm sends out
myservo.attach(D0); // attach the servo on the D0 pin to the servo object
myservo.write(35); // resets the servo by moving it to 35°
pinMode(D7, OUTPUT); // set D7 as an output so we can flash the onboard LED
Spark.function("servo", updateServo);}int updateServo(String command){ uint8_t pos= command.toInt(); // convert string to integer
}void servo(const char *event, const char *data) // be accompanied by a string.
{if(strcmp(data,"Toggle")==0) // if the string is "Toggle", ring the bell multiple times.
{ myservo.write(0); // move servo to 0° creating a ringing sound
digitalWrite(D7, HIGH); // flash the LED
delay(50); // wait50 ms
myservo.write(35); // reset the arm before ringing again
delay(50); myservo.write(0); delay(50); myservo.write(35); delay(50); myservo.write(0); delay(50); myservo.write(35); delay(50); myservo.write(0); delay(50); myservo.write(35); delay(50); myservo.write(0); digitalWrite(D7, LOW); // turn off LED
}elseif((strcmp(data,"Off")==0)){ myservo.write(35); // reset the servo position to resting postion of 35°
}}
Clock
Arduino
Allows the photon to read the current time and send a signal to the others when the desired time is met
#include <Grove_LCD_RGB_Backlight.h>rgb_lcd lcd;const int colorR=200;const int colorG=200;const int colorB=200;void setup(){ lcd.begin(16, 2); // set up the LCD's number of columns and rows: lcd.setRGB(colorR, colorG, colorB); // Set up background backlight color lcd.print("Tom's Clock"); Time.zone(-5.00); delay(1000);}void loop() { lcd.setCursor(0,1); // sets the cursor where the LCD displays the time lcd.print(Time.format(Time.now(), "%T")); // display the current time on the LCD if (Time.hour() == 17 && Time.minute() == 16 && Time.second() == 05){ // checks for when the alarm is set Particle.publish("alarm1234","Toggle",PUBLIC); // sends a signal to the other photons delay(1000); // give a 1 second delay to allow the signal to be sent to both photons Particle.publish("alarm1234","Off",PUBLIC); // sends an off signal to the other photons }}
