We accept character by character from the serial buffer sent by the app and combine them to form a string.We then compare it to the command. If it matches, the command is carried out. For example, when the string we receive is &#34;Right&#34;, the bot turns right.<h3 >Connections:</h3>Find all connections here :<a
