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.

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);
