Week Mar 29 to Apr 5

Hardware List (complete list of hardware and received/not received status)

• Bluetooth shield: Ordered
• RFID Reader: Received
• Arduino
• Servo Motor
• LED NEOPIXEL
• Powerbank
• Lock
• 3D Printed Casing

Week APR 6 to Apr 12

Hardware Components

• Bluetooth module: Uses SPI protocol (this should be Serial, Bluetooth uses Serial, not SPI). Library exists. Yes I have tested it with some code
• MFRC522 RFID: Uses SPI protocol. Library exists, MFRC522 library. Yes I was able to get the examples to work.
• Servo Motor: Uses Serial communication (this should be direct GPIO connection: servo uses one digital pin, not Serial). Has libraries but are not required to use servo. Yes I have coded using it.
• LED Neopixel: Uses serial communication (this should be direct GPIO connection: Neopixel uses one digital pin, not Serial). Has it's own libraries. Yes I have used it before.

Week APR 19 TO APR 26

Note: I have expanded my project to take a picture when a person is in front of the lock and when a person requests access to open the lock, similar to the "ring doorbell". I have switched to a Raspberry Pi because it is more compatible with a camera.

Completed:

• I have all the materials
• I've printed my 3D casing
• I've controlled the servo from the Raspberry Pi
• I've experimented with the camera for the Pi (Took a picture and recorded video)

Still Working on:

• Programming a method to control the servo (1 day)
• Programming a method to get the camera to take a picture when a button is pushed and/or when a person is detected (1 day)
• Getting Raspberry Pi to work with Blynk (1 day)

Roadblocks:

• I tried powering the servo with a 9V battery and 2 AA batteries but it wouldn't work. So far it only works using power from the Raspberry Pi. I will try to get a Powerbank to see if it will work. After a period of time the Raspberry Pi freezes as you can hear towards the middle of the video. I believe that is a power issue.
• Choosing appropriate programming language (JS, Python or C). I am using Python right now.
• Learning how to use Raspberry Pi GPIO pins
• Generating code to control motor and take picture
• Getting Raspberry Pi to work with the Blynk App
• Putting all the hardware together
