Exercise 2: Using Flex Sensor to indicate availability

Use Scenario

When I'm working on my desk in the studio, I often get disturbed by peers wanting to chat or ask a question. This sometimes breaks my flow of work and I would really appreciate a subtle way of communicating when is it okay for someone to disturb me and when it's an absolute DND. Therefore, I hope to design a phone holder that gives out warnings when I pick up the phone.

Input:

- Switch: turn the light system on/off

- Flex Sensor (FSR): sense the bend

Output:

- Switch: turn the light system on/off

- (when the flex sensor is bent halfway): low brightness of LED

- (when the flex sensor is all the way): high brightness of LED
