E-Textile Logic Injector – Debugging Tool

The e-textile logic injector tool enables the injection of a high (1) logical state into a digital circuit. With this tool, makers can simulate a digital write high (digitalWrite (pin, HIGH)) before writing any code. This enables them to test their circuitry for shorts, loose connections, and polarity before adding complexity through code.

To use the tool, disconnect your microcontroller from power (recommended), then attach one alligator clip to your board’s GND pin and the other clip to the magnet on the logic injector. Press the probe against any thread that you want to inject a signal into and then press the button on the logic probe to test the component (video).
