Unformatted text preview: Display this value of the temperature on the first line of your LCD as follows: Reading: XX.XF You can use Fahrenheit or Celsius. 2) Create a set-point temperature using the push button GPIO on your microcontroller board. This is the threshold temperature above which an alarm will go off if the reading exceeds this value. Display this value on the second line of your LCD as follows: Setpoint: XX.XF Use any two of the external GPIO buttons to increment or decrement the tenths value of the setpoint value. Make the button increment/decrement upon a button push, but continuously increment/decrement when holding the button down. 3) Configure the buzzer to sound when the reading exceeds the setpoint value. You should use Timer1 PWM to do this so the buzzer sounds continuously in this condition. As soon as the temperature reading drops below the setpoint value, the buzzer should turn off again....
