I'm desperate, I don't know what is the problem. I'll explain all.
I have bought 4 devices (SparkFun Single Lead Heart Rate Monitor - AD8232 - SEN-12650 - SparkFun Electronicshttps://www.sparkfun.com/products/12650), medical electrodes and these wires https://www.sparkfun.com/products/12970. I've got Arduino UNO and the software required.
I have powered the devices with 3.3V and GND(from Arduino), I connect all the wires like a Hookup Guide (https://learn.sparkfun.com/tutorials/ad8232-heart-rate-monitor-hookup-guide?_ga=1.225843482.1432040408.1441193009):
Output -> analog pin 0
LO- and LO+ --> Digital pin 10 and 11
And I have used the arduino code used in hookup guide, but I've always obtained this when I open serial plotter in Arduino software:
I connect the electrodes in my arm wrists and the RL signal in ankle.
I don't know why, any help please??
Thank you in advance.
