When All You Have is a Hammer

via Nuts and Volts

A friend in the marketing business contacted me about a project for a local retail store. He wanted to track customer satisfaction as customers exited the store by placing an Arduino-controlled survey taker. Customers would press one of five buttons as they left, indicating their experience from Very Satisfied to Not Satisfied. My friend envisioned five buttons connected to an Arduino, an LCD display, perhaps a beeper for button press feedback, and a battery pack capable of supporting the device for a week.
