# Test firmware
Use this firmware to test all hardware components of a Pentabug. Add a
`pentatonic` extension and press all buttons. The buttons test the following
components (from left to right):
Use this firmware to test all hardware components of a Pentabug. It can test
nearly all hardware features of the device.
* flash LED 1
* send IR signal; receiving this signal flashes LED 2
* plays (lower) tone using BUZGND
* plays (higher) tone using BUZZR
* starts the vibration motor
The following things exist in all modes:
This test should catch most obvious errors, but not all possible errors. Some
pinouts are not tested (e.g. JP3 and some pins of JP4 and JP5).
* right LED is on when IR signals are received (use a remote or first mode to
test)
* pressing the right button activates next mode
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)
