Circuit Documentation

Summary

This circuit involves an Arduino UNO microcontroller interfacing with an EMG sensor and two servos. The EMG sensor is powered by two 9V batteries and sends its signal to the Arduino, which then controls the servos based on the sensor input.

Component List

1. EMG SENSOR

   • Description: Measures muscle activity by detecting the electrical potential generated by muscle cells.
   • Pins: +Vs, GND, -Vs, SIG

2. 9V battery

   • Description: Provides power to the circuit.
   • Pins: +, -

3. Arduino UNO

   • Description: A microcontroller board based on the ATmega328P, used for prototyping and development.
   • Pins: UNUSED, IOREF, Reset, 3.3V, 5V, GND, Vin, A0, A1, A2, A3, A4, A5, SCL, SDA, AREF, D13, D12, D11, D10, D9, D8, D7, D6, D5, D4, D3, D2, D1, D0

4. Servo (2 units)

   • Description: A rotary actuator that allows for precise control of angular position.
   • Pins: gnd, vcc, pulse

Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino UNO. The setup() function is where you initialize your components and settings, and the loop() function is where the main logic of your program runs repeatedly.
