Modified Ninja

I was not satisfied with either US eyes or a Ledmatrix.
With some -rather rough- modifications I was able to position the 16x8 Led matrix as a mouth underneath the eyes.

I studied ways to have US sensor, buzzer, pushbutton and ledmatrix and I found as the best way this wiring:

A0 = Pushbutton (switches to +)
D0 = GPIO16 US Echo pin
D1 = GPIO4 SCL (I2C)
D2 = GPIO5 SCA (I2C)
D3 = GPIO0 Right Foot
D4 = GPIO2 Right Leg
D5 = GPIO14 US Trigger pin
D6 = GPIO12 Buzzer pin
D7 = GPIO13 Left Foot
D8... (More)

OttoNinja Code from Github .. doesn't work?! [SOLVED NOW] Hi Camilo Parra Palacio, hi Sebastian Coddington, I am trying to commission the Ninja with the OttoDIY ESP8266 Board.

So downloading the newest Arduino libraries First: The Arduino IDE 1.8.13 refuses "" as non valid library, so ist doesn't work as described at Github. Second: fixed Third: Extracted and moved the directories under "src" into the Arduino library folder and the "examples" content to the sketchbook folder. Restart Arduino IDE. The OttoNinja_APP.ino is the only example I could compile.... (More)
