EE445L Project Ideas 

Bluetooth Exchange data with a cell phone
  -  Microcontroller side using SNP running on CC2650
  -  Cell phone side using LightBlue on iPhone
  -  Cell phone side using BLE Scanner on Android
  -  Volume 3, Section 9.4
  -  Starter code See Application Processor example of Real-time Bluetooth MOOC
  -  Starter code See Chapter 6 of Real-time Bluetooth MOOC

Wifi See EE445L Lab 4.

Near Field Communication (NFC) technology Remote sensing
  -  Battery-less NFC/RFID Temperature Sensing Patch
  -  NFC Sensor Tag Application Example
  -  MIKROE-1726
  -  NFC Key Fob - NTAG216

Dual channel stereo audio output
  -  Dual channel DAC like the TLC5618ACP (similar to Lab 5)
  -  Two TPA731 Class AB amps TPA731 (same as Lab 5)
  -  One dual channel AB amp like the TPA6017A2
  -  Drive two separate speakers or drive a three-pin headphone jack

Sub-1 GHz Sub-1 GHz can span 20 km on a coin cell battery. See LAUNCHXL-CC1310

File System Volume 3 Chapter 8. Implement FAT file system on the ST7735R SDC Starter project SDCFile_4C123.zip

Scanned Keyboard Connect multiple keys to the microcontroller. Volume 2 Section 4.10, see aLec51.ppt, Starter project MatrixKeypadPeriodic_4C123.zip

LED Matrix see aLec51.ppt Example 4 by 4 LED matrix interface For this example, a 2mA LED needs 4*4*2=32mA on the column drive, and 4*4*4*2=128mA on the row drive.

Accelerometer This 2-axis accelerometer is easy to solder ADXL202.pdf. You connect the two outputs to input capture pins, and use the timer to measure pulse width. The best way to add acceleration is to get a module (chip soldered onto a board) from a hobby store like Sparkfun, Adafruit , or Pololu.

Solid State Relay turn on/off AC appliances.See Section 6.5.2 in Volume 2. You interface it like an LED. One place to buy surplus SSR is All Electronics

Stepper Motor See Example 2.3 in Volume 2. See Section 4.7.2 in Volume 2. Starter project Stepper_4C123.zip. One place to buy surplus stepper motors is All Electronics

DC motor and servo Motor Control DC and servo motors with fixed period, variable duty cycle digital output. The EE445M has two DC motors and a servo.
