Sarah’s Final Project Progress


I started testing my circuit on Tinkercad. I’m using a Feather Huzzah board to connect to 2 sets of LEDs and a Hall Effect Sensor (HES). Because the HES turns the LED’s on/off I’m unsure whether the HES output is the LED input. I know the LED needs to receive code info from the Arduino so I made two circuits. One where the HES output in the LED input and the other where they are both connected to different pin #s. I’m confused if either is correct.

I linked the IFTTT Fitbit applet to Adafruit IO. The applet should trigger at a certain time and send Adafruit IO information on my daily steps but so far it has not worked. It was saying that the ‘there is an issue with the trigger’ I reconnected my Fitbit app to IFTTT it no longer says there is an issue but it has not fired and there has been no update on the IO.


I assume I will have to set multiple of these applets for the different times of day I want to be updated on my steps instead of it automatically updating.

I am using the Fitbit App on my phone as my step calculator. Could that be the issue?
