                ESP8266 Introduction
              
          
    #Overview
The ESP8266 is a versatile chipset that provides client and access point wifi capabilities, on-chip SRAM and flash storage, a RISC processor, GPIO pins, and pin outs for memory and CPU extensability. Bundled as a series of modules with varying features focused around acting as either a wifi extension module to an existing microcontroller or as an self-contained solution for integrating wifi and internet functionality with GPIO control. From an application standpoint, the ESP weighs in as an inexpensive and compact alternative to AVR (arduino) based, wifi-driven IoT solutions.

## simple_programming_problems
Elementary

Write a program that prints ‘Hello World’ to the screen.
Write a program that asks the user for her name and greets her with her name.
Modify the previous program such that only the users Alice and Bob are greeted with their names.
Write a program that asks the user for a number n and prints the sum of the numbers 1 to n
Modify the previous program such that only multiples of three or five are considered in the sum, e.g. 3, 5, 6, 9, 10, 12, 15 for n=17
Write a program that asks the user for a number n and gives him the possibility to choose between computing the sum and computing the product of 1,…,n.
Write a program that prints a multiplication table for numbers up to 12.
Write a program that prints all prime numbers. (Note: if your programming language does not support arbitrary size numbers, printing all primes up to the largest number you can easily represent is fine too.)
