esp8266_reaction_time

This program is intended to test your reaction time. The built-in LED will flash after some random delay and you are supposed to press FLASH button as soon as possible.

How it works

1. The program starts a timer with 1 ms interval.
2. Interruption handler adds 1 to the interruption counter;
3. When a user presses the button
   1. if LED is disabled print too soon message and exit interruption handler
   2. otherwise print INTERRUPTION_COUNTER variable and set the variable to 0

There's an additional variable called START_NEW_GAME which is used in the main loop to wait until the currect game finishes.
