Tell us about yourself!
In step 6, part 2, definitely follow instructions on mounting the servo coupler. They are super tight but using a screw to tighten down worked great.
So excited about this design, i have to give a sneak peak of what i'm working on...
I'm super stoked to have a ESP32 in this HackerBox, been trying to get my hands on one since they came out. Looking forward to working with this new board/chip...on some GoCubes!!!

i agree, joystick would be better. Though I'm having issues making even this method work. I noticed when i press left it was going right. And when I used right, only one wheel turned, the other didn't turn in opposite direction like it does for the Left turn mode. Reverse doesn't do anything for me. I'm i doing something wrong with the setup in Blynk? I assigned pin V2 to right and v3 to left, plus v1 to reverse.
