Voice Control, 3 AAA battery version of Elektro Robot. TT 220:1 gearmotor.

My first version of Elektro was a 2 AAA battery version. This one has room for a 3 AAA battery holder so that you do not need a voltage boos regulator for the White LED eyes or if you add the Voice recontion chip.
I am using a TT gearmotor with a 220:1 gear ration, you can find them on Aliexpress.
The programable voice recontion chip can be found on Aliexpress as well. Links in the video discription on YouTube.
