Muscle control
Use forearm or jaw muscle activity to control motors, games, keyboards, and superhero-style builds. This is the main path for Arduino EMG and Spiker:bit projects.

If you are searching for Arduino EEG, Arduino EMG, EKG/ECG, or micro:bit neuroscience projects, start here. Backyard Brains body-signal builds turn real muscle, heart, brain, and blink activity into microcontroller inputs for classroom experiments.
Signal map
Older BYB experiments use Arduino language. Newer classroom builds usually use Spiker:bit and BBC micro:bit. The signal names should stay honest: EMG is muscle, EEG is brain rhythms, EKG/ECG is heart timing, and eye-blink projects use activity near the temples.

These projects are not forced into broad categories. The labels describe the biological signal where it is clear: EMG for muscle, EKG/ECG for heart timing, EOG for blink control, and EEG only when the build is actually about brain rhythms.

Build a working bionic hand and control it with forearm muscle contractions.

Use a muscle flex to trigger a wrist-mounted servo launcher.

Read left and right muscle signals and turn them into directional controls.

Flex your forearm to cycle letters, choose characters, and type with muscle signals.

Build a wearable alarm-smacking servo that makes a muscle flex part of the wake-up routine.

Build a physical helper that presses the spacebar when you flex.

A two-player reaction build: wait for the cue, flex, and fire first.

Read heartbeats, monitor intervals, and write code that reacts to pulse.

Use eye-blink activity near the temples as a threshold input.

Translate muscle gestures into Morse code, tones, or simple messages.

Conduct a digital orchestra using forearm signal strength.

Use a jaw-clench signal as a digital threshold for audio samples.
What you need
Core board
The core board for turning biological signals into micro:bit inputs.
Robotics build
A ready-made motorized build for EMG control and neuroprosthetics demos.
Classroom set
Scale the activity for labs, workshops, or classroom teams.
Arduino EEG and Arduino EMG
The older Arduino EEG and Arduino EMG experiments are still useful for advanced builders and archive readers. For most new classrooms, Spiker:bit is the cleaner path: it lets students record real EMG muscle signals, explore ECG/EKG and EEG concepts, and use body signals as micro:bit inputs without starting from raw amplifier design.
FAQ
No. Backyard Brains has older Arduino EEG and Arduino EMG experiments, but the current classroom-friendly microcontroller path is usually Spiker:bit with BBC micro:bit. This page helps visitors find the right EEG, EMG, EKG/ECG, or blink-control path without mixing them into fake categories.
Most starter builds use EMG muscle signals. Spiker:bit documentation also discusses ECG/EKG heart signals and EEG brain signals, while Blink:Bit-style builds use eye activity near the temples.
No. These are human physiology and body-control projects. They use muscle, heart, eye, jaw, and gesture signals to control microcontrollers.
