A simple and interesting project to work with Arduino Uno.
Note this is an educational project and the design goal is not a professional tool.
| items | #Q |
|---|---|
| Arduino Uno Board | 1 |
| 5V relay module | 1 |
| Jumper board wire | 1 |
| The cable connecting its board to the computer (such as the connecting cable of the printer) | 1 |
| TM1637 seven-segment 4-digit display module | 1 |
| 4.7 kilo ohm resistance with 0.25 watt power and 5% tolerance | 1 |
| temperature sensor (DS18B20) | 1 |
| Cooler (Fan => 12V) | 1 |
| heater (low-ampere filament lamp) | 1 |
| 12V-2A Adapter (Independent power source for cooling and heating control) | 1 |
With the help of a temperature sensor, a cooler (fan) and a heater (low-ampere filament lamp), we keep the temperature of the chamber constant, for example, the temperature of the chamber should be 25 degrees Celsius.
If the temperature drops, the heater starts working to increase the temperature
If the temperature rises, the cooling circuit turns on and the chamber temperature decreases.
In this way, the temperature remains constant
Note Don't forget to download the libraries included in this repository to run the code correctly. The path to install libraries in Arduino software : Sketch > Include Library > Add .ZIP Library…
- Connect the Arduino board to the computer via USB cable.
The first method
- After running the Arduino software, click on the New option through the File menu.
- Paste the codes placed in file Temperatur-ctrl in the new window
- Now select the Save option from the File menu and save the program in your desired location.
- After saving the program, go to the Board menu through the Tools menu and select the Arduino Uno item from the drop-down list.
- Go to the Port menu again through the same Tools menu and select the USB port number through which the Arduino board is connected to the computer from the drop-down list.
- In the end, to transfer the program to the Arduino board, it is enough to click on the upload icon to program the program on the Arduino board in the Arduino software.
The second method
- After running the Arduino software, click on the open option through the File menu.
- and open file Temperatur-ctrl
- After openning the program, go to the Board menu through the Tools menu and select the Arduino Uno item from the drop-down list.
- Go to the Port menu again through the same Tools menu and select the USB port number through which the Arduino board is connected to the computer from the drop-down list.
- In the end, to transfer the program to the Arduino board, it is enough to click on the upload icon to program the program on the Arduino board in the Arduino software.
After entering the necessary codes, connect the board to the computer through a serial port and from the serial part of the monitor, we can set our desired temperature by entering the number of that temperature. You can also connect the board to your phone with a OTG Make these settings using the Serial USB Terminal program tool, which is the same as the serial monitor of the Arduino editor
