Hello,
i want to make easy to use bot and found this... Before wasting my money... Is there any way to make a user interaction? (Ex.: if i type !help it sends a message with help)

Great idea btw! Keep it up :)

I am using ArduinoIDE, and the code is black here, because the colors are seen better on black. (Website setting)

Yes, there is a trick:
The “For” loop does not have {}, that is reason why you might think it does not do anything. But.... it does something:
Whenever the command is executed, it tells the servo, witch direction is witch, that helps unbug the code.
