Introduction

This project is from Microcessor Design class at the University of Seoul. Developed with JKit-128-1.

This project is mood light with convenient features such as:

1. Light detection: Light is automatically on at night.
2. Double clap detection: User can toggle the light with a double clap.
3. Sound threshold adjustment: User can adjust the threshold sound value. Every sound bigger than the threshold is checked whether it is a doble clap.

Configuration & Build

1. Setup hardware

   • Board: JKit-128-1

   • Paripararls

     Component Name	Prefix	Manufacturer
     Rotary Encoder	P1	SunFounder
     RGB LED Module	P2	SMG
     Sound Sensor Module (TS0223)	P3	SMG

   

2. Install AVR-GCC

   We used avr-gcc-7.3.0-atmel3.6.1-arduino7-i686-w64-mingw32 compiler which can be downloaded from the link below.

   http://downloads.arduino.cc/tools/avr-gcc-7.3.0-atmel3.6.1-arduino7-i686-w64-mingw32.zip

3. Install make

   We used make-4.4.1 make program which can be downloaded from the link below.

4. Build project

   mkdir build
   cd build
   cmake\
       -DAVR_TOOLCHAIN_DIR=${Fill in path to the folder containing AVR-GCC bin folder}\
       -DCMAKE_MAKE_PROGRAM=${Fill in path to make.exe}\
       ..
   

5. Upload the executable to your machine using avrdude
