A good friend of mine who’s a teacher was doing quizzes in her class making students compete to answer questions… resulting in them complaining they raised their hands before the others.
I decided to give her this quiz show type buzzer for Christmas to solve her problems.
When one of the players press it’s button (the fastest player wins this), the led of the right colour lights up saying he’s in control… and no other buttons from the other players work, until the master of the game decides if the answer is good or not by pressing a little button on the main unit, giving a point or not to the player in control.
If you have any questions, comments, constructive criticism… don’t hesitate to write 🙂
Oh and you can like my video on YouTube, that would be nice 🙂
P.S. There is a little problem with the display that I couldn’t figure out how to solve. When playing a tune, the display doesn’t light up anymore, like if no current goes to it anymore… anybody has an idea what the problem could be or how to fix it in code ? See the video if you don’t understand what I mean.
Step 1: Components
- Rocker Switch
- ATmega328
- Ceramic Resonator 16MHZ
- 5V wall adapter power supply
- Barrel jack
- Hook-up wire (black, red, green, white, yellow)
- Heat shrink tubing
- Big buttons (green, blue, yellow, red)
- Some LEDs
- Serial 8 Characters x 7 Segment LED Display
- Prototyping board
- Tamiya connectors (male, female)
- Some resistors (1x100ohm (for the speaker), 5x150ohm (for the leds), 6x10KOhm (for the buttons))
- Push buttons (2)
- Speaker wire
Step 2: The Plan
Sorry for my writing… I know it’s not a very professional plan, but if I have more time I will make a better one and replace it… feel free to ask me anything about it if it’s not clear 😉
