4 years ago @indrawanfian if you are a beginner better just use Otto Blockly directly https://www.ottodiy.com/#blockly no need to worry about libraries that seems you have not installed.
Once you fill confident follow the process well to install Arduino libraries, https://www.arduino.cc/en/Guide/Libraries
Also detailed in full documentation of Otto https://wikifactory.com/+OttoDIY/otto-diy
sorry i'm beginner and i want to build ottoDIY, but i just get error compiling just shown on the picture. even though I already entered the otto libraries file into the arduino libraries
