Create a custom Secret Santa trivia box with Arduino
Participating in Reddit’s Secret Santa this year, hacker “Haxxa” decided to go all out, picking out not only several gifts for the recipient, but an Arduino-powered trivia box to house them in.
In use, an Arduino Nano onboard feeds queries to the gift recipient on an LCD display, allowing them to answer using one of three buttons. When 20 questions have been answered correctly, the box unlatches via a servo motor.
In addition to the physical items inside, the project also generates its own web page, revealing digital gifts to go along with the physical items!
To open the box, my giftee must complete the trivia game, there are 25 questions all based around my giftee’s interests, posts and hobbies. Once complete they will be rewarded with the gifts inside. I also included a wireless access point which activates upon completion of the game. Connecting to this access point reveals a website with more digital gifts including subscriptions, more games and challenges.
You can see it in action below and find its code over on GitHub.
