Description

This design is for a pillbox that automatically opens and closes 3 boxes based on a user input timer system. There is also an interrupt button that closes the boxes, a buzzer to alert users, and an LCD to display extra information to the user. The full arduino code is as follows : #include <Servo.h> #include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 8); Servo myservo1; Servo myservo2; Servo myservo3; const int beeper = 13; int buttonState = 0; int opn = 40; int closed = 130; int pos1 = closed; int pos2 = closed; int pos3 = closed; int delay1=0; int delay2=0; int delay3=0; int delay4=0; int delay5=0; void setup() { myservo1.attach(10); myservo2.attach(9); myservo3.attach(6); lcd.begin(16, 2); lcd.clear(); myservo1.write(pos1); delay(1000); myservo2.write(pos2); delay(1000); myservo3.write(pos3); attachInterrupt(0, blink, CHANGE); pinMode(beeper, OUTPUT); Serial.begin(9600); Serial.println(" "); Serial.print("How many seconds from the start until Box 1 opens: "); delay(3000); if (Serial.available()) {delay1= Serial.parseInt(); } Serial.println(delay1); Serial.print("How many seconds between Box 1 and Box 2 opening: "); delay(3000); if (Serial.available()) {delay2= Serial.parseInt(); } Serial.println(delay2); Serial.print("How many seconds between Box 2 and Box 3 opening: "); delay(3000); if (Serial.available()) {delay3= Serial.parseInt(); } Serial.println(delay3); Serial.print("How many seconds between Box 3 opening and refilling pills: "); delay(3000); if (Serial.available()) {delay4= Serial.parseInt(); } Serial.println(delay4); Serial.print("How many seconds between refilling pills and Box 1 opening: "); delay(3000); if (Serial.available()) {delay5= Serial.parseInt();} Serial.println(delay5); delay1=delay1*1000; delay2=delay2*1000; delay3=delay3*1000; delay4=delay4*1000; delay5=delay5*1000; delay(delay1); } void loop() { if (pos1==closed){ for (int i=500; i>0; i--) { digitalWrite(beeper, HIGH); delayMicroseconds(i); digitalWrite(beeper, LOW); delayMicroseconds(i); } } pos1=opn; myservo1.write(opn); lcd.clear(); lcd.print("Take pills from"); lcd.setCursor(0,1); lcd.print("box "); if (pos1==opn){ lcd.print("1 "); } if (pos2==opn){ lcd.print("2 "); } if (pos3==opn){ lcd.print("3 "); } delay(delay2); if (pos2==closed){ for (int i=500; i>0; i--) { digitalWrite(beeper, HIGH); delayMicroseconds(i); digitalWrite(beeper, LOW); delayMicroseconds(i); } } pos2=opn; myservo2.write(pos2); lcd.clear(); lcd.print("Take pills from"); lcd.setCursor(0,1); lcd.print("box "); if (pos1==opn){ lcd.print("1 "); } if (pos2==opn){ lcd.print("2 "); } if (pos3==opn){ lcd.print("3 "); } delay(delay3); if (pos3==closed){ for (int i=500; i>0; i--) { digitalWrite(beeper, HIGH); delayMicroseconds(i); digitalWrite(beeper, LOW); delayMicroseconds(i); } } pos3=opn; myservo3.write(pos3); lcd.clear(); lcd.print("Take pills from"); lcd.setCursor(0,1); lcd.print("box "); if (pos1==opn){ lcd.print("1 "); } if (pos2==opn){ lcd.print("2 "); } if (pos3==opn){ lcd.print("3 "); } delay(delay4); pos1=opn; pos2=opn; pos3=opn; for (int i=500; i>0; i--) { digitalWrite(beeper, HIGH); delayMicroseconds(i); digitalWrite(beeper, LOW); delayMicroseconds(i); } myservo1.write(pos1); myservo2.write(pos2); myservo3.write(pos3); lcd.clear(); lcd.print("Refill the pills!"); delay(5000); pos1=closed; pos2=closed; pos3=closed; lcd.clear(); myservo1.write(pos1); myservo2.write(pos2); myservo3.write(pos3); delay(delay5); } void blink() { if (pos1==opn){ pos1=closed; myservo1.write(pos1); } if (pos2==opn){ pos2=closed; myservo2.write(pos2); } if (pos3==opn){ pos3=closed; myservo3.write(pos3); } lcd.clear(); for (int i=0; i<500; i++) { digitalWrite(beeper, HIGH); delayMicroseconds(i); digitalWrite(beeper, LOW); delayMicroseconds(i); } }
