Arduino Coding Process

S T E P 1 : TESTING THE PIR SENSOR

To test whether the PIR sensor worked, we created a code that would light up an LED every time movement was detected by the PIR sensor. We then coded in a time delay of 6 seconds which the light would remain turned on for. We would then aim to swap in a relay module component instead of the LED, which would control the air compressor.

S T E P 2 : BRIDGING PIR SENSOR AND RELAY MODULE (ination)

In order to change the LED component to a relay module, we had to alter the code slightly to specify the link between the PIR and relay componets. We used the same Digital pin and time delay of 6 seconds, however now when motion was detected by the PIR sensor the green light on the relay would turn on for 6 seconds before switching o. When the relay is connected to the air compressor, this would inate the balloon for 6 seconds.

S T E P 3: BRIDGING PIR SENSOR AND SERVO-MOTOR (deation)

e nal step was to code for deation immediately aer ination had stopped. is required the coding of a linear servo component that’s cog would spin 180 degrees, pushing the linear actuator into the deation valve for 6 seconds. Aerwhich, the cog would spin another 180 degrees, returning the linear actuator to its initial state. e entire process is ready to be repeated again if motion is detected by the PIR sensor.
