How to send two ADC value via ARDUINO?

[nishat anjum khan]

for my project i have to send two adc value and then have to plot it individually in MATLAB...can anyone give me suggestion that how can i send two ADC value via ARDUINO?

You have to use ADC and Serial library.

what is your connection? usb serial parallel?

where x is adc channel

                       // outside leads to ground and +5V
int val = 0;           // variable to store the value read
 
void setup()
{
  Serial.begin(9600);          //  setup serial 9600 bps baudrate
}
 
 
void loop()
{
  val = analogRead(analogPin1);    // read the input pin
  Serial.println(val);             // debug value
  delay(500);
  val = analogRead(analogPin2);    // read the input pin
  Serial.println(val);             // debug value
  delay(500);
}

Hi

Would be good if you could let me know of a safe link to download the Arduino Uno Library for Proteus.

Seems there are a few links when you google but don't know which ones are safe and actually work .

thanks

Hi wp100

I downloaded from here.

https://www.zer07even.com/download/125-arduino-library-proteus-untuk-simulasi

https://arduiny.com/how-to-simulate-arduino-with-proteus-isis/

After installing go to Proteus library and search for Arduino. It will show Arduino and Emulator (2 entries). Select Emulator. The 3 boards are in that.

Hi Milan

Have loaded it in without any problems, well get some .hex loaded up tomorrow and give it a good test; will save me having to drag the dev board out all the time.

Many thanks
