Using an Arduino microcontroller to code the following project: Detect a person's presence and trigger electrical items to flicker on and off sporadically. Do this with physical computing using: - two digital inputs (this could be a button, light sensor, toggle) - two LEDs (or a motor, or something else you can turn on/off) - code to make it blink in different patterns depending on which button(s) is pressed Please write the code using Arduino that would complete this project and explain the steps to complete the physical computing on a controller board..
