# Test firmware
Use this firmware to test all hardware components of a Pentabug. It can test
nearly all hardware features of the device.
nearly all hardware features of the device. It offers the following features:
The following things exist in all modes:
* right LED is on when IR signals are received (use a remote or first mode to
test)
* pressing the right button activates next mode, plays a sound using BUZZR
Here is a description what happens on a right button press in which mode:
* activate left LED and send IR signal
* activates motor
* plays sound using BUZZGND
* activates all pins on the extension board for a short time (add a penetatonic
to get feedback on all but one of those pins)
* the left led blinks when no input is present
* receiving an IR signal activates the right led
* pressing the left button sends an IR signal (triggering the right led)
* pressing the right button activates the motor
* each button plays a sound using a different pin of the buzzer
* the pins of the extension board are constantly cycled through (add a
pentatonic to visualize all but one pin)
