LAB TASK 6
LAB 6
Lab Tasks 1.
Three different temperature sensors are connected to RB1, RB2 and RB3. If the temperature
observed at any of the sensors exceeds the specific threshold, an alarm alert is generated by a
Green LED connected at RC4. Implement the above task with microcontroller PIC18 F452 in
Proteus. Use Switches with RB1, RB2 and RB3 to simulate the effect of sensors.

TASK 2:
2. Modify the above program by connecting two extra LEDs Blue and RED, with RC5 and
RC6. Now three will be following alarm updates. a) Turn on Green LED if any one of the
sensors sends an alarm. b) Turn on Blue LED if any two of the sensors sends an alarm. c)
Turn on RED LED if all of the sensors sends an alarm.
