Heat Alarm
I want to make some thing to cooling , but there is problem happen when i was connect Fan to motor. So I decide to delay it to next week and make heat alarm circiut.
Tinker Cad
Arduino IDE
Arduino Uno 3
Breadboard
Temperature sensor
Piezo buzzer
Jumper wires
330 Ohm Resistor
LED
Software &
At first I draw connection and workflow on paper then, I am go to Tinkercad to test it on simulation.
I start by connecting the Temperature sensor to Arduino, I was taking sensor read at analog A5. then connecting buzzer and led in parallel, give arduino order to turnon led and buzzer when tempreture exceed 90C.
I was Tring other connections, but due to polarity of buzzer this is the one available for one pin from Arduino.
I start coding by make Arduino take read of temp. from the TMP36 sensor then make it compare it. if it more than 90C, I program Arduino to turn on Buzzer and led for alarm.
Am just here change the temp. alarm will alert at because, I dont want to use fire ti heat my alarm.
Step 1: I am just wired the circuit like how it on the Thinker cad.
Step 2: I am open Arduino , select Board as Arduino UNO, then Select the port I but, Arduino on, from tools.
Step 3: Then copy the code from Tinker cad to Arduino IDE.
Step 4: Then I change the code to be suitable for LM35 Data sheet.
Step 5: Then verify the code, then send it to Arduino.

I discover you may be need motor driver with Arduino not only when you use device need more than 5 v but, also some time the current outcome from Arduino is weak to make your device work.
I discover that when I start doing my project at fan and didn't work, I ask Farida & Saaid and they figure out it will be current.
