In this lesson you will learn exactly how to use parseInt from the Arduino Serial library to convert multiple characters to a single integer. Get ready!\u003cbr/\u003e\u003cbr/\u003eOVERVIEW\u003cbr/\u003eLet’s do a quick overview of what we’ll cover.\u003cbr/\u003e\u003cbr/\u003eA quick overview of Serial Communication\u003cbr/\u003eSerial.read() vs Serial.parseInt()\u003cbr/\u003eCode for converting chars to integers with parseInt()\u003cbr/\u003eparseInt() details, like setTimeOut(), Lookahead Mode, and ignore\u003cbr/\u003eQuick Serial Communication Review\u003cbr/\u003eIf you watched our lesson on using serial.read(), then you already know how to take serial input and convert the chars to integers by putting all the incoming bytes into a char array. If you want to learn that method, make sure to check out the lesson on Serial.read().\u003cbr/\u003e\u003cbr/\u003eThat code worked great, but it was somewhat lengthy. In this lesson we are going to talk about using a function from the Serial library called parseInt().\u003cbr/\u003e\u003cbr/\u003eLet’s do a quick review of how serial communication works with Arduino.\u003cbr/\u003e\u003cbr/\u003eYou Arduino has some hardware on it called a USART/UART that will allow you to receive data serially from a computer. It will store that data in a buffer called the serial receive buffer.\u003cbr/\u003e\u003cbr/\u003eWHAT’S A BUFFER?\u003cbr/\u003eNow if the word buffer throws you off – don’t sweat it. You can think of a buffer like a bunch of horse stalls in a stable. Some stables are big and have a bunch of stalls – you can house a bunch of horses there, other stables are quite small, and you only have room for so many horses – you can’t take in more horses than you have stalls!\u003cbr/\u003e\u003cbr/\u003eA buffer is like a stable, but instead of having horse stalls, it has spaces in memory where data can be stored.\u003cbr/\u003e\u003cbr/\u003eGenerally speaking, a buffer is a transient place for data storage in a program. Usually, you are receiving data into a buffer, and then reading it out pretty quickly – because more data will be coming in and you need to make space for it. This is not some hard and fast rule though.\u003cbr/\u003e\u003cbr/\u003eThe serial receive buffer has room for 64 bytes. When data comes to your Arduino over Serial, each byte will end up in the serial receive buffer.\u003cbr/\u003e\u003cbr/\u003eIt’s your job as the programmer to read the data out of the serial receive buffer and do something with the data.\u003cbr/\u003e\u003cbr/\u003eBut how do you do that?
