  7.40 - Grove - Project 1: Control the LED blink rate with a potentiometer
  
  Control how fast an LED blinks with a potentiometer.

  Simply turn the pot one way to speed up blinking, and the other way to
  slow it.
  
  
  Components
  ----------
  - Grove Base Shield
  - An Arduino Uno compatible board (such as Arduino/Genuino Uno or Seeeduino)
  - Grove - potentiometer
  - Grove - LED kit with a red LED
  - Two Grove cables
  - Optional: a mounting piece of cardboard with nylon nuts, bolts and spacer.

  IDE
  ---
  Arduino IDE
  
  Libraries
  ---------
  - None
  
  Connections
  -----------
  - Use a Grove cable to connect the potentiometer module to Grove connector A0.
  - Use a Grove cable to connect the LED kit module to Grove connector D4.
