Steps On the breadboard, build two bi-directional motor control circuits (also known as “H-bridge”) circuits. These circuits will control the two DC motors that drive the wheels. Each circuit will have two wires from the Arduino (one for forward, one for backward) to control the circuit, and two wires from the single DC motor that […]
Topics: Overview Hardware A Basic Schematic Diagram Resistors Reading Resistor Values Putting it Together Trying it out! More on Resistors and LEDs Software Comments Variables Procedures References Project 1.Overview As mentioned earlier, Arduino consists of two major parts: the hardware (the Arduino board) and the Software (the IDE). The advantage of using the Arduino is […]
This circuit is designed for tracking the location of vehicles. Most oftracking systems are made by using GPS. This is very simple and cheap. Tracking systems are mostly used by fleet operators for tracking a vehicle location, routing and others. This is a very good method for preventing our vehicles from stolen. This tracking system […]
This project describes how you can build a mobile real time GPS tracker with integrated Google Maps. I began this project mainly to see if I can integrate all the different pieces of hardware and software to make a workable solution, and it took some time, but finally when everything was said and done, it […]
UPDATES October 30, 2013 – 7PM (GMT+2) The new official name for this app is ArduDroid and it can be installed from Google Play. I changed the name to avoid a naming conflict with another app. September 15, 2013: I Have won a Nexus 7 tablet for this project part of a competition held […]
If you’re a fan of the Harry Potter series then we also bet you were pretty taken with Hogwarts headmaster Dumbledore’s pensive—the magical object that could not only store memories, but actually let people fall into and re-experience the events. This week’s Instructables How-To from aspiring Tel Aviv-based hacker and inventor, Zvizvi, shows you how […]
This example shows technique for calibrating sensor input and shows the sensor outputs by controlling LEDs and SSD, also shows how to monitor the state of a switch. Hardware Required 8 LEDS 2 push button switches 2 sliding switches 4-SSD with MAX7221/7219 LM35 Speaker Circuit In this circuit according to the above diagram 8 LEDs […]

This foot pedal plugs into the Arduino case which plugs into your PC via microUSB cable. Arduino microcontrollers can easily be used to power fun projects like robots and even sending tweets to Twitter but they’re versatile enough to turn up in the strangest of places – like under your feet. We had a question […]
MQTT is a lightweight messaging protocol for the Internet of Things. This post details the use of Stream support for large payload storage in the Arduino MQTT library. MQTT is a lightweight protocol, but that doesn’t mean that the payloads have to be small. The spec was designed to allow for messages up to 256MB, […]
