HOMOTRONICS

HOMODRUINO®

The iHackRobot series represents a progression of intuitive machines (IM) that have developed over time. These IMs can be programmed to perform various tasks by integrating the knowledge you’ve gained from our previous projects. They can autonomously navigate within a confined space, or be controlled via your keyboard, a TV remote, ethernet, wifi, bluetooth, and other sensors such as light, sound, and line detectors.

Our past projects involving RGB LEDs, IR remote controls, the SR04 ultrasonic finder, the L239D motorshield, the HC-05 bluetooth module, and the Arduino R3 Uno board can all be amalgamated to construct this programmable entity, which I’ve named Homotronics®.

A more advanced task would be to develop a simple, modular sketch for its neurotronic brain that can control its movement range, a feature I’ve termed the SOUL (Spectrum Of Ultrarhythmic Locomotion). The sketch provided below serves as an excellent starting point for instilling SOUL into these robots.

Arduino Ethernet Shield

How to setup an Ethernet Shield on an Arduino and a Webserver to control an LED:

by J.B. Wylzan

Project 29: Ethernet Web Server

This project shows how to set up the Arduino Ethernet Shield,
design a simple HTML code, and use the site to control an LED and a relay.

The Ethernet Shield

The Web Server

The Relay

Hardware:
ethernet shield
relays
leds
resistors
connecting wires
breadboard
Arduino R3 UNO board

Block Diagram:

Replace the servo with a relay instead.

NOTE: Before you try the sketch below , make sure to test your ethernet shield using the example provided by Arduino. Go to File > Examples > Ethernet > Webserver.
