Nunchuck Password Lock

Using what we have learned in our Sensor and Peripheral (ECE 153B) class, we will attempt to create a direction combination password using a Wii Nunchuk controller. 

The idea, the block diagram. Originally our plan was to create a bluetooth NES controller.

Peripherals: 

1. D pad (UART)

2. Buttons (2) (UART)

3. Select & start function buttons (priority UART)

4. Bluetooth peripheral interface. (I2C)

We realized the internal components of the NES controller were far too to reverse engineer and came with no documentation online, so we pivoted our approach. 

We ordered a Wii Nunchuk I2C adapter so we could interface with a Nunchuk and created a new block diagram. 

We also began working on our code to interface with the Nunchuk.

We added servo functionality from Lab 6 after finishing Nunchuk interfacing.

We then created a state machine to act as our password manager.
