Instructables user RoysterBot was tasked with building a quiz show style button system for a company get together:
If you have ever watched a TV quiz show you have probably seen contestants trying to press a button in order to win a chance to answer a question. The contestant’s quick reaction time results in some kind of light and/or sound indicating victory. This is a practical way to choose the next focus of the game’s activity and it adds a bit of excitement to the process. So when the holiday party planning committee decided to have a trivia contest I decided to build a quiz contestant lockout system to add an extra dimension of fun to the festivities. This would help the planning committee’s mission of creating some entertaining activities for the event.
The minimum requirements were to have a system with multiple buttons that contestants press for a chance to answer a question. The first one to press the button would lock out the other contestants. The system would need to have a simple way to quickly identify who pushed their button first. And finally the system would need to be reset for the next round.
He accomplished this by building a Arduino-based central controller linked to four project boxes that featured the Staple’s Easy Button as call-in buttons for the contestants. His build guide is extremely thorough and although the project is a big one to bite off as a beginner it’s definitely a great start to working with Arduino chips. Check out the full guide at the link below.
