Spiker:bit - Muscle EMG Sensor Kit for Micro:bit Projects
Spiker:bit is a micro:bit EMG and muscle sensor kit for classroom neuroengineering, maker projects, and body-controlled inventions. Use surface electrodes to record EMG muscle activity, connect the signal to BBC micro:bit, and build with Microsoft MakeCode blocks, JavaScript, or Python. Students can use real muscle activity to trigger servos, lights, games, robotics, web-flinger builds, and neuroprosthetic hand demos without starting from raw amplifier design. BBC micro:bit sold separately.

Build micro:bit projects from real muscle signals
Spiker:bit is a micro:bit EMG sensor and micro:bit muscle sensor board for students who want to turn biological signals into code, motion, games, and robotics. Connect surface electrodes, read muscle activity as a micro:bit input, and use Microsoft MakeCode to control servos, lights, motors, robot hands, and classroom neuroengineering inventions.
Use Spiker:bit when the goal is an EMG muscle sensor kit that moves quickly from physiology to making: flex a forearm muscle, set a threshold in MakeCode, and trigger a servo or micro:bit project that responds to the body in real time.

Recording-focused labs
If the main goal is to record and study EMG physiology waveforms, use the Human SpikerBox. Spiker:bit is built for micro:bit control, MakeCode, servos, games, robotics, and classroom invention.
Still using the retired Arduino Muscle SpikerShield? The original Arduino code and schematics are preserved in our archive. For new classroom EMG, servo, robotics, and MakeCode projects, use Spiker:bit with BBC micro:bit.
Product FAQs
Is Spiker:bit an EMG sensor for micro:bit?
Yes. Spiker:bit is a micro:bit expansion board that lets students use surface electrodes to record EMG muscle activity and turn that signal into micro:bit inputs for MakeCode projects.
What can students control with EMG muscle signals?
Students can use muscle activity to trigger servos, lights, games, robotics, web-flinger builds, neuroprosthetic hand demos, and other threshold-based microcontroller projects.
Does Spiker:bit require Arduino?
No. Spiker:bit is built for BBC micro:bit and Microsoft MakeCode, including block-based coding, JavaScript, and Python pathways.
Can students use block coding?
Yes. Spiker:bit works with Microsoft MakeCode for micro:bit, including block-based coding, JavaScript, and Python pathways.
Is Spiker:bit a medical device?
No. Spiker:bit is for education, classroom demonstrations, and maker projects. It is not for diagnosis, treatment, or medical monitoring.

Spiker:bit Projects
Spiker:bit turns EMG, EOG, and EKG biological signals into micro:bit inputs students can use in MakeCode projects. Start with a threshold-controlled servo, then move into games, robotics, classroom demos, and wearable inventions that respond to real physiology.

EMG
Prosthetics
DIY Neuroprosthetic Hand
Build a servo-powered prosthetic hand that closes when forearm EMG crosses a threshold, then tune sensitivity and timing like a real neuroengineering control system.
EMG
Launcher
Spiker-Man Web Flinger
Turn forearm EMG into a wearable servo trigger, connecting muscle recruitment, threshold code, and a dramatic MakeCode-controlled web launcher.
EMG
Maze
Muscle Maze
Map muscle intensity to servo motion and steer a physical marble maze, giving students a tactile way to debug thresholds, latency, and motor control.
EMG
Typing
MyoTyper
Use EMG pulses as an accessible text-entry switch, then explore how timing, false positives, and signal fatigue shape real assistive-device design.
EOG
Alertness
The Snooze Smacker
Use eye-closure signals to trigger a servo response, then tune the delay so students can reason about EOG thresholds, attention, and signal noise.
EOG
Blinks
BlinkBit
Convert eye blinks and eye movements into micro:bit inputs, opening projects around communication, switching, and the difference between EMG and EOG signals.
EKG
Heart
Heart Signal ECG
Place electrodes in a simple Einthoven triangle, switch Spiker:bit into heart recording, and graph rhythmic heartbeat spikes in MakeCode before turning them into micro:bit inputs.
EMG
Reaction
Cowboy Duel
Build a two-player reaction game where muscle activation, timing windows, and micro:bit logic decide who fired first after the signal.
EMG
Game
Dino Jump
Make a browser game jump from an EMG flex by turning muscle threshold crossings into a physical button press students can see, adjust, and test. -
