in R

1-Using the IDLE, write the Python script singleloop.py and execute. Show the results and explain the code.

2-Run Arduino script heat-fan for at least one cycle of heating and cooling. Record your temperature readings in a CSV text file using Geany. Plot your data. Show your script, data file and graph.

// control fan and heater // to measure temperature changes next to a resistor int heaterPin = 10; int fanPin =9; // edit the following values in minutes as needed int fanTime=5; int heatTime=5; int repeatTime=5;

void setup(){ pinMode(heaterPin, OUTPUT); pinMode(fanPin, OUTPUT); Serial.begin(9600); }

void wait_min(int duration_min){ // messages and allow time to measure Serial.println("You can read several values of temperature"); Serial.println("Try to take readings every 0.1C or at least every 0.5C"); for(int i=1; i<=duration_min;i++){ delay(60000); Serial.print(i); Serial.print(" min "); } Serial.println(""); }

void loop(){ Serial.println("Started with heater off"); digitalWrite(heaterPin,LOW);

Serial.print("Now turning fan on for "); Serial.print(fanTime); Serial.println(" minutes"); digitalWrite(fanPin,HIGH); wait_min(fanTime); Serial.println("Turned fan off"); digitalWrite(fanPin,LOW); Serial.print("Now turning heat on for "); Serial.print(heatTime); Serial.println(" minutes"); digitalWrite(heaterPin,HIGH); wait_min(heatTime); Serial.println("Turned the heater off"); digitalWrite(heaterPin,LOW); Serial.print("The loop will repeat in "); Serial.print(repeatTime); Serial.println(" minutes"); wait_min(repeatTime); }
