+Reverses the value of the analog rotary reading, which reads the resistance of the rotary so 0 becomes 1 and 1 becomes 0. 
+The rotary increases in resistance as the rotary is turned, while the light sensor decreases it resistance as light intensity increases.
+The led_set_blink_rate() function is fitted to the light sensor read values and set to decrease blinking speed the higher the value.
+This function can be used to reverse the value of the registered rotary resistance value so it can be used with the LED blinking function.
