Inspiration - Music
What it does - Plays music easily. (with hand shake)
How I built it - arduino, laser diods, photoresistors
Challenges I ran into - We had to make photoresistor system work well, also we had to solve problem about arduiono and sound frequency.
Accomplishments that I'm proud of - We finally finished our project correctly and made it cool entertaining gadget.
What I learned - I learned the system of sound frequency and how to make the code a real thing.
What's next for Laser DJ - I think we can develop this gadget by adding lots of new combined sounds and make it available for everybody.
