In mBlock 3.2.2 there are Arduino commands available like ‘read pulse’ and ‘set digital pin’ which makes mBlock useful for the community members not using specific mBot parts or robots. After downloading the beta version 3.3.0 is seems that al these default arduino instructions have been removed and replaced by very specific mBot component instructions like ‘set 7-segment display’ etc.
Please keep the 3.2.2 Arduino instructions in the Robots scripts!
