We first worked on the basic circuit for the IR-beam sensor with a simple LED indicator light that sensed if something was dropped into the Tip jar.
We then added the Servo motor as an additional output along with the simple LED indicator. The servo motor was used to actuate the ‘blooming of the flower’ in response to a Tip given - either dropped into the Jar or Swiped by card on the Register.
Once the servo motor was suitably calibrated, the ornamental LEDs on the flowers were added.
We then worked on getting the same response to a tip made by swiping a card to the register. Assuming the Cash Register to be in the form of a Google Sheet, we worked on connecting the Google sheet input to the system. This was done via IFTTT RSS feed.
Is this a good/useful/informative piece of content to include in the project? Have your say!
