assign 0 as its initial value.

Add a repeat block and set the repeat times to 180(180 angles). Drag a “change variable” and a “servo” block and put

them in the repeat one. Name the variable “angle” and select the mode “++”. Set Servo PIN to IO4 and degree to the

named variable. Don’t forget to delay 15s.
