Next steps:

Midway of the project I realized that the pressure sensor might not be able to measure bottle weight and the way to overcome this is by using a load cell in combination with HX711 ADC instead of the pressure sensor. Since the phy comp lab does not have these components, I had no way to get them except order in Amazon. I have just received the HX711 ADC, but still waiting on the load cell. Once I receive them, will complete the final version of the actual working pill reminder.
