Hello, I recently bought the SHIELD-EKG-EMG shield to use on my arduino uno r4 wifi. Without the use of any library utilization I tried to read the analog input from the boards as suggested by the page 8 of this pdf(https://www.olimex.com/Products/Duino/AVR/OLIMEXINO-2560/resources/Olimex2560-EKG.pdf) however even without putting the electrodes on anything I get the same analog reading of 302 and the serial plotter doesn't show anything meaningful. Please help.

If you have no electrodes you should receive a flat line.

Make sure proper AIN is selected on the board and in the code. Make sure the proper serial port is used.
