Arduino SD Cards and Datalogging – Circuit Schematic
Arduino SD Cards and Datalogging
Now that we`ve covered the basics in tutorials 1-10 (you have watched them all right! ), it`s time to start pursuing some more complex projects! In this episode...
Arduino RFID Door Lock – Circuit Schematic
Arduino RFID Door Lock
The first step to building a RFID door lock with a basic Arduino is to bread board out a basic working arduino. Most Arduino pre-flashed ATMega 168 chips come w...
Arduino powered GLCD (Graphic LCD) – Circuit Schematic
Arduino powered GLCD (Graphic LCD)
Displays are always nice. So far I`ve just been demonstrating how to use 7-segmented displays to display numbers using very few resources. But what if you want ...

Arduino multi-mode lamp with soft touch switch
In this Arduino-based project, we will build a lamp with multiple light displays: color sequencer, dimming light, color chaser, firelight all selected by a touc...
Arduino Liquid Crystal Displays – Circuit Schematic
Arduino Liquid Crystal Displays
I had initially planned to do an LCD tutorial a little further down the line, but there was very high demand for it, and I already had a circuit assembled for t...
Arduino FM radio receiver shield – Circuit Schematic
Arduino FM radio receiver shield
This Instructable will show you how to build your own FM radio receiver shield to be used with an Arduino board. The radio chip we are going to be using is the ...
Arduino Audio DAC Options – Circuit Schematic
Arduino Audio DAC Options
DAC is short for Digital to Analog Converter. In this article we play around the code Michael Smith created for a PWM based DAC. I modified his code so that oth...
Arduino 7 segment Displays Digital Clock With Charlieplexing LEDs – Circuit Schematic
Arduino 7 segment Displays Digital Clock With Charlieplexing LEDs
This is my second instructable. I just had a mood of making a digital watch. But wanted to make it a learning process. I already had a sanguino i could have eas...
Arduino 2-axis servo solar tracker – Circuit Schematic
Arduino 2-axis servo solar tracker
I marked the approximate center of the base and drilled a hole large enough to screw the setscrew for the servo armature in. I then hot glued the armature to th...
Android talks to Arduino board – Circuit Schematic
Android talks to Arduino board
This project slightly modifies the Google Android sample app called Bluetooth Chat  so you can type a message in the Android app and that same message will ap...

Analog Clock And Temperature sensor On An Oscilloscope using Arduino
Scopeclock is an easy to use hardware to make your X-Y capable analog oscilloscope more useful. Using this simple to use hardware you can convert your analog os...
All in one Remote using Arduino – Circuit Schematic
All in one Remote using Arduino
August, 2007One of my other hobbies is photography, and, about a year ago, I purchased a new digicam a Panasonic FZ30. I joined the Panasonic forum on the dprev...
AC Arduino dimming circuit – Circuit Schematic
AC Arduino dimming circuit
I am not an engineer, just an experimenter and hacker and prototyper etc, so, thanks to people who know a lot more than I do, I learned that this is not safe to...
Arduino Button – Circuit Schematic
Arduino Button
Connect three wires to the Arduino board. The first two, red and black, connect to the two long vertical rows on the side of the breadboard to provide access to...
Arduino Blink – Circuit Schematic
Arduino Blink
To build the circuit, attach a 220-ohm resistor to pin 13. Then attach the long leg of an LED (the positive leg, called the anode) to the resistor. Attach the s...
Arduino While Loop – Circuit Schematic
Arduino While Loop
Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while ...
Arduino Tone 3 – Circuit Schematic
Arduino Tone 3
Power your three FSRs (or any other analog sensor) with 5V in parallel. Connect each sensor to analog pins 0-2, using a 10K resistor as a reference to groud on ...
Arduino Shift Out – Circuit Schematic
Arduino Shift Out
At sometime or another you may run out of pins on your Arduino board and need to extend it with shift registers. This example is based on the 74HC595. The datas...
Arduino Serial Call Response – Circuit Schematic
Arduino Serial Call Response
This sketch sends an ASCII A (byte of value 65) on startup and repeats that until it gets a serial response from the computer. Then it sends three sensor values...
