Need

Question: Is there enough flour and sugar at home to make a cake for your friend's birthday tomorrow? Or do you need to stop at the store on your way home?

Concept

Design containers for pantry bulk items that relay content levels to smart phone app in real time.

Equipment

  • Arduino
  • Sharp GP2D120XJ00F Analog Distance Sensor 4-30cm
  • Container
  • Computer

Prototype

(coming soon)

Code

int IRpin = 1;   
int val = 0; 
                                          
void setup() {
Serial.begin(9600);                             
}
   
void loop() {
float volts = analogRead(IRpin)*0.00322265624;
float distance = 12.21*pow(volts, -1.15);         
Serial.println(distance);                                                             
}
