We got the Servo Add-on and built the Dancing Cat as per instruction.
I reset the mBot to factory firmware/default program.
I connected it to my Makeblock Android App with Bluetooth and launched the mode to remote control the mBot in Dancing Cat mode. Moving in all directions works perfectly fine. However, the arms don’t move when I slide the Servo button left or right.
When I switch the mBot on the arms wiggle for maybe 1 second/1millimeter.
Do you have any idea what went wrong? Thank you.
