Temperature Controlled DC Motor | Arduino TINKERCAD

Hello there

This is my first ever project which i had published on Instructables.

This is the project which have been prototyped virtually using TINKERCAD website.

Components used procedure

Virtual prototyping:

1. Arduino UNO R3
2. Temperature sensor TMP36
3. NPN Transistor.
4. DC Motor
5. Bredboard
6. connecting wires.

Connection should be given as per in the picture.

• First connect power pins to the breadboard
• connect vcc to the emitter
• Base to pin5
• collector to DC motor
• Connect vout to the analogue inout A0
• Power and ground connections should be given properly.

#define TEMPERATURE A0

#define MOTOR 5

void setup()

{

Serial.begin(9600);

pinMode(MOTOR, OUTPUT);

}

int speed_decider(int temp)

{

if(temp<35)

return 0;

else if(temp>40)

return 255;

else

return map(temp, 35, 40, 0, 255); }

void loop()

{

int temperature = analogRead(TEMPERATURE);

temperature = map(temperature, 20, 358, -40, 125);

Serial.println(speed_decider(temperature));

analogWrite(MOTOR, speed_decider(temperature));

}

After giving the same connections you can simulate this on tinkercad.

• the temperature values are given to the microcontroller as analogue input via pi A0
• the input value is variable of the function

int speed_decider(int temp)

• The value is returned to the calling statement on void loop()
• To the DC motor speed control
• The speed of motor will be varied from 4360-7800 Rpm with respect to 35-40 degree celcuis.
• There is no motor driver used here instead of that we are using NPN transistor.

And the real prototype also will work with the same circuit.
