Muscle-EMG-Sensor

Part of this section was covered in the first week assignment, to make it easier I’m reproducing it here in part:

The dream:

Years ago, while researching for didactical approach teaching nervous system, I stumbled on an electronic device measuring the electrical impulsions created when one individual muscle flexes. This was from Instructable website ( https://www.instructables.com/id/Muscle-EMG-Sensor-for-a-Microcontroller/ ). This prototype offered a simple, yet efficient breadboard device interfaced with an Arduino to display the muscle contraction electrical traces on a computer screen.

Having no prior experience in such electronics field, I resorted to approach the problematic task on my own and following trials and errors I was able to make an oversized, breadboard circuit which can be seen here (well what’s left of it!!!):

This prototype, although cumbersome and balky, yielded functionality and proved to be very useful at the time for our course curriculum. For this reason and for durability qualities, transportation and to facilitate handling around a biology laboratory classroom, I want to translate this device into a case enclosed pcb. It could ultimately be built into series to share with other Adults Education Center offering same high school science and technology program we are. It would from outside look a little like this (Reproduced from Advancer Technologies, https://github.com/AdvancerTechnologies):
