More and more makerspaces around the world are looking to add coding and electronics to their maker education programs. One of the best ways to do this is by integrating an Arduino board into makerspace projects and lessons. We’ve found that a lot of maker educators haven’t taken the plunge into coding or Arduino because they think programming is scary. Because of this, we wanted to make sure this tutorial was written for the absolute beginner with no experience whatsoever. This tutorial is a high level view of all the parts and pieces of the Arduino ecosystem. In future posts, we will take you step by step in creating your first simple Arduino project.
Line Follower robot is a machine that follows a line, either a black line on white surface or vice-versa. Nowadays, every robot is done with the help of the microcontroller, and hence the circuit is too big and tough to understand and makes it costly. For these reasons, in this project we have developed an intelligent Line follower robot with a simple concept with simple circuitry. Basically, there are two types of line follower robots: one is black line follower which follows black line and second is white line follower which follows white line. Here we have designed the first one. Line follower actually senses the line and run over it.
There are different ways to program the ESP8266, but I'll only cover the method using the Arduino IDE. This is really easy for beginners, and it's a very familiar environment if you've used Arduino boards before. Just keep in mind that it's not limited to this option: there's also an official SDK available to program it in real C, this is very useful if you want to optimize your code or do some advanced tricks that aren't supported by the Arduino IDE. Another possibility is to flash it with a LUA interpreter, so you can upload and run LUA scripts. Or maybe you're more familiar with Python? Then you should check out the MicroPython firmware to interpret MicroPython scripts. I'm sure there's other languages available as well, so just do a quick Google search and write your code in the language of your choice.
