Prompt Title: Arduino Harry Potter Buzzer.

Sure, I can definitely act as your teacher and guide you through the process of learning electronics and programming. Let's break down the process into smaller, more manageable steps so that we can work on them one at a time. Here's a possible schedule:

1. Introduction to Electronics and Arduino Programming: We'll start by covering the basics of electronics, such as Ohm's Law, Kirchhoff's Laws, and basic circuit components like resistors, capacitors, and diodes. We'll also cover the basics of Arduino programming and how to use the Arduino IDE. Estimated time: 1-2 weeks.

2. Building a Simple Doorbell: Once you have a good grasp of the basics, we'll move on to building a simple doorbell that is powered by 120V AC current with a 9V battery backup. We'll also integrate the low power indicator that we have already discussed. Estimated time: 2-3 weeks.

3. Weatherproofing and Mounting the Button: Once we have a functioning doorbell, we'll work on making it weatherproof and mounting the button outside. This will involve choosing the right enclosure and sealing it properly to prevent water and dust from getting inside. Estimated time: 1-2 weeks.

4. Connecting to a WiFi Camera: With the doorbell working and weatherproofed, we'll move on to connecting it to a WiFi camera that can feed video to an Android smart TV. This will involve learning how to program the camera and interface it with the doorbell. Estimated time: 3-4 weeks.

Of course, this is just a rough schedule, and we can adjust it as needed to suit your pace and level of understanding. Let me know if this works for you, and we can start by diving into the basics of electronics and Arduino programming.
