On this instructable I will try to show how to interface a RFID sensor with the Arduino. I am using the RFID sensor from seeedstudio the serial version of it. There are a few parts you will gonna need. I also bought some RFID keys. UPDATE: Now it works with IDE 021 Step 2: Plugging

Hello! This is the cheapest and easiest way to make a two-dimensional laser show projector. It uses just one pivoting mirror, powered by the focusing mechanism from a CD or other optical drive. They said it couldn’t be done, but Ljudmila‘s skunkworks GRL research facility delivers anyway! 😉 This design was first discovered in 2006

I’ve always been interested in monitoring my local weather, and noticed the difference between what weather.com and accuweather.com think my local weather is, and what I see out the window. I also wanted better control over my heating and A/C system. As a computer and electronics nut, I’ve been playing with the Arduino Microcontroller, and

At this point you should have a robot that can think on its own, we need to be able to tap into its thought process. See what he sees. Make some of his decisions for him. in essence, we need to be able to guage his intelligence to make him more intelligent and increase his

I do a lot of projects with Arduino’s and breadboards. Often as I work on a messy workbench, the Arduino or breadboard get jostled and the wires pop out of the headers or the breadboard. To solve this problem, I decided to make a simple acrylic stand for mounting an Arduino and a breadboard that

Greetings, One late night of web surfing I came across some 45 Degree Extension boards. Thinking to myself “Wow!” that’s cool and then I looked at the price…$27.00 before S&H. “Yikes!” I’ve been looking for an excuse to learn Eagle PCB layout software and this was the project I decided to cut my teeth on…”Wing

Morse code was the breakthrough that made possible long-distance communication in the era of the telegraph. The code represents alphanumeric characters by short and long intervals of signal — those familiar dots and dashes. For many years passing a Morse code test was a prerequisite of getting a Ham license, but nowadays most radio amateurs

INTRODUCTION In the guide, I will explain how I managed to send data back and forth between a PC and Arduino via a cheap Bluetooth HC-05 transceiver, which can be found for less than $10 on ebay with the breakout board. The version I have used in this project does not have a breakout board so
