Arduino Ethernet Shield – Control an LED from PC

Ethernet Shield

Ethernet Shield allows an Arduino to to connect to the internet and to read and write a microSD card. This shield use Wiznet W5100 ethernet chip. Inside this chip, there are PHY, MAC, IP, and TCP layer. The advantage of using this shield over the ENC28J60 is the TCP/IP stack is already implemented by hardware on this chip. With the ENC28J60 chip the TCP/IP must implemented on the microcontroller that is interfaced to it. In this tutorial, I will explain how to control an LED from PC using this shield.

Arduino ENC28J60 Ethernet Module – Ping Test from PC to Arduino

ENC28J60 Ethernet Module

ENC28j60 is a low cost Ethernet chip. It contains Ethernet PHY layer and MAC layer. The IP layer and TCP layer (TCP/IP stack) are implemented in software. The data-rate of ENC28j60 is limited to 10 Mbps. In this tutorial, I will explain how to use the ENC28J60 module with Arduino.

Arduino LCD16x2 Shield

LCD16x2 Shield

LCD16x2 shield is an Arduino shield that also comes with 6 buttons. All of the buttons on this shield are connected to the Arduino by using just one GPIO pin. In this tutorial, I will explain how to use LCD16x2 shield with Arduino Uno. This product is compatible with Arduino LCD library (LiquidCrystal.h). There are 5 buttons in this product (up, down, left, right, and select) that can be used for make a project such as display menu items and select them with the buttons.
