Specific value Voltage generator by PCF8591 module for Arduino boards.
- Open the project by platformio (platformio.org)
- Build and upload the project to your arduino board
- make connection between your Arduino board and PCF8591 module
- Input your a specific value in Serial monitor of Arduino IDE between 0.00 <value<5.00 ; for example 0.01 or 3.75
- You will see the voltage output on the pin AOUT of PCF8591
- Use/install the library in /lib (PCF8591.zip)
- Move the code from /src/main.cpp to your project .ino
- Build and upload the project to your arduino board
- make connection between your Arduino board and PCF8591 module
- Input your a specific value in Serial monitor of Arduino IDE between 0.00 <value<5.00 ; for example 0.01 or 3.75
- You will see the voltage output on the pin AOUT of PCF8591
If you want to flash the code to your Arduino board by Arduino IDE, move the code inside /src/main.cpp to the main code of your Arduino IDE project (.ino) and install the library inside /lib (PCF8591.zip) to your Arduino IDE, then build & upload.
