I am a newbie in arduino. I have a idea to make a project to display a system status on a 3.2 LCD TFT screen but I would like to minimize necessary modules to be used. The system is like that,
12V DC input, 3 modules to 5V, one for the arduino, the other two are connect two USB ports, a 12V DC fan (3pins or 4pins), the speed of the fan depends on the temperature of the system that read from arduino.
I want the 3.2 TFT screen to display the following information
- Date, time and temperature
- the voltage and current of main power supply (that is the 12V DC)
- the voltage of the two USB ports individually and current used by the devices (that is the voltage and current output from individual USB port)
- the voltage, current and RPM of the 12V DC fan.
The other information like alarm, warning messages I think I can handle, my main concern is what component and modules I should use. Does this project can completed by using only one arduino board? As it contains a 3.2 screen and about 6 sensor modules
