Pulsey the Pulse Robot is a robot that detects human's pulse and reacts accordingly. It uses two blink M RGB leds as its eyes. It uses the servo motor to represent the robots heart-shaped hair. Both the servo motor and the RGB leds react to the human pulse detected from the pulse sensor. Once a pulse is detected, the RGB LEDs fade to a shade of green (much like the green of the pulse sensor). The servo turns once a pulse is detected.
There are also two potentiometers. One is used to control the HSV of the eye LEDS when it does not detect a pulse. It can be rotated to make the eyes into diverse colors. The other potentiometer is used to adjust the brightness of the eyes therefore giving much more of the color palette. If the brightness is totally reduced, the robot will not light up its eye LEDs unless a pulse is detected.
