With the module I bought, the electrode leads are coloured: Yours may be coloured differently. TM1637 4-digit 7-segment When an action potential occurs in a cell, the cell next to it is triggered. What pin are you using?Disconnect the AD8232 module from the analog input then try altering the input voltage - connect it to 0V or 5V or a 1.5V battery. It wouldn't be allowed for a medical device but for a domestic device it probably would be allowed. For power, you can use 4 AA cells or a single Lithium cell. Each of the seven LEDs is called a segment, because when illuminated, the segment forms part of a numeric digit (both decimal and hex). It seems that most of the noise is mains hum. The AD8232 chip contains a high quality, low noise instrumentation amplifier and signal conditioning to remove noise. For initial testing, I connected the LO+ and LO- pins to two LEDs though 1k resistors to ground. It's not a very realistic fake but it produces pulses of about the right size at about the right frequency. // On my Uno and Mega the "button" is just a piece of wire inserted into pin 7.
