Physical Computing Week 4: Analog Output

The Conversation Balancer is a physical device that helps balance conversations, making sure that all participants are contributing about the same amount to a conversation. I implemented a prototype for two-person conversations with two buttons, two LEDs, a servo, and a piezo speaker. Each participant has to “check in” by pressing their button when they start speaking. A servo-controlled meter is displaying the current balance of the conversation, and the speaker buzzes when the conversation becomes unbalanced (which happens when one of the speakers is speaking more than 75% of the time).
