Adjustable Wireless Neuro Stimulator System

This project is made for the Design Project lecture. With this system, you can control output current by using Android application which made with App Inventor.

Notes

• The maximum output current is 5.5mA.
• The maximum Pulse High, Pulse Low, and Working Time values on the application are 255.
• Current source and system power supplies must not share the same ground.
