Node MCU Arduino IDE in Ubantu

Install Arduino IDE on Ubuntu

1. Download Arduino linuxIDE from https://www.arduino.cc/en/main/software
2. Extract it (tar xvf FILENAME)and Runit (./install.sh)

USB Serial Port Setup

In order to upload code an arduino board over USB, you need to add your user to the `dailout` group and connect the snap to the `raw-usb` socket. Open a terminal window, run the following commands an *reboot* your computer.

> `sudo usermod -a -G dialout $USER`

> `sudo snap connect arduino:raw-usb`

Now restart your computer and you're good to go!

Mussle Stimulater with AVR 32

1. At the beginning its gives good output with 3 mS period frequency and 5~18 V output voltage range. This is need to be update while testing....! 

 

 This module were used to drive output in between 5~18 V range, this can operate maximum of  125 nS frequency, 

  2.  when current pass through skin 6 mA it can feel for above period(3 mS)

  3. This is 1st day test and will update with latest improvement soon
