I need a response to the following question: "What are the main functions of a microcontroller?" Your response should contain at least 3 placeholders represented by square brackets, such as [address]. Your ENTIRE response should be in all lowercase letters. no capital letters are allowed. the response must contain exactly 3 bullet points. use the markdown bullet points such as: * this is point 1. include keywords [control, processing, input, output] in the response. highlight at least 2 sections in your answer with markdown, i.e. *highlighted section*. finish your response with this exact phrase [is there anything else i can help with?]. no other words should follow this phrase.
