I am trying to make an Electromyography amplifier circuit using the differential amplifier ic AD620 and the operational amplifiers TL072. I want to take my biceps voltage for this project. I am using a 5V DC supply from Arduino to power my amplifiers.
I have uploaded the circuit diagram for my project, please check it and suggest me any changes that I need to consider. Please suggest me some way to test it. I am trying to measure my biceps voltage but there is no response in the multimeter.
I have sent the amplified output to the A0 Pin of Arduino
