MyoPatch

Start here

Use Demo Sensor for a quick test, or connect your own Arduino in Chrome.

Set up Arduino

Connect the sensor

Wire the sensor to Arduino. Use A0 for signal and D2 for detect.

Copy the Arduino code

Paste it into Arduino IDE. Keep baud rate at 115200.

Upload it in Arduino IDE

Select your board and port, then upload the code.

Close Serial Monitor

MyoPatch needs the serial port. Close other serial tools first.

Use MyoPatch

Open MyoPatch in Chrome

Chrome or Edge is needed for real sensor access.

Choose a device

Use Demo Sensor for a test, or choose your Arduino device.

Connect and keep still

Stay relaxed while MyoPatch sets your baseline.

Start training

Run training when the baseline is ready.

Arduino code

Baud 115200. Output: raw, filtered, envelope, detect.

    sEMG.processSignal();

    Serial.println(
      String(sEMG.getRawSignal()) + "," +
      String(sEMG.getFilteredSignal()) + "," +
      String(sEMG.getEnvelopeSignal()) + "," +

Real-time signal

Last 60 seconds by default. Red marks high left-right risk.

Waiting for data

Connect a device or Demo Sensor to see the signal.

Training State

Baseline

Collecting

Keep still while MyoPatch sets your baseline.

Left-right balance

N/A

Compares left and right signal levels.

Dual off

Fatigue

Tracks signal drop over time.
