Quit pulling your hair out over incorrect passwords. Using an Arduino Leonardo and Adafruit’s NFC shield, you can unlock your computer with an NFC card. The Arduino reads the NFC card’s unique identifier and once it receives the correct one, it uses the Arduino Leonardo’s keyboard emulation feature to type a password. Step 1: Parts […]

Arduino Mini-Shields
This is a set of simple, small form-factor, mini-shields that I created almost by accident. As I made more and more of them, I realized that they could be really useful. What started out as a way to use some spare parts, turned into a standardized form factor for a versatile, miniaturized Arduino shield. The […]
Making a program start using a switch
Connecting the Switch To connect the switch to the Arduino, you will need the switch, two jumper wires, and a 10kΩ (brown-black-orange) resistor. Once you have all the required parts, you will need to wire the switch to the Arduino using the breadboard. NOTE: The virtual board may be slightly different from the physical one. […]
ArduinoISP Bootloader/Programmer Combination Shield
I started recently to get interested in building Arduino based robots. Since it is a traumatizing process to take any creation apart, I am opting to keep mine alive and kicking. To lower the cost of this strategy it seems obvious to switch from the arduino development board to selfbuilt arduinos – DIYduinos if you […]
Arduino Light Following Robot
Overview This instructable will use three photoresistors (light dependent resistors) and an Arduino to control the motion of a robot. Any common robot chassis can be used for the robot. The light sensors will be mounted on the left side, right side and front of the robot. When light of sufficient intensity falls on a […]
A wireless voice-controllable household system
Motivation top We design a smart home control system which allow people control their home devices by voice command at home. This is a wireless, voice control system. People could control almost all the facilities at home including lights, fans or even back ground music. Right now, the basic function of lights control, fan control […]
Arduino desktop application on java in LAN
Description: here we have created an java desktop application using neatbeans. this application turn on led on arduino. this application also work in your LAN. Step 1: Assigning MAc and IP to Arduino board UPLOAD THIS PROGRAM TO ARDUINO. ALSO CHANGE YOUR MAC AND IP ACCORDING YOUR NETWORK. /* UDPSendReceive.pde: This sketch receives UDP message […]
Magpi: The Micro Arduino Gaming Platform Interface
Here’s a retro hand-held gaming console I built with my son. It uses an Arduino micro-controller, a small LCD screen, push-buttons, a 3D printed case and home-grown “PC” board. It’s really pretty easy to solder and put together. My son & I wrote two games and a drawing program for it. See the video for […]
Arduino Double Dice Jewelry Box w/ Secret Switch
This was a fun project. Push the red button, watch the dice ” ROLL ” then stop on a random roll most every time. The hart of this game is the ATMEL ATmega328P on a stand alone board. Powered by 4 AA NiMD batteries. Can you find the SECRET SWITCH in the main picture? Where is […]
D.I.Y Pneumatic Linear Actuators
The D.I.Y. movement has many implications for the future of creativity and commerce. The impact of inventing what one needs rather than purchasing it promises to be empowering, fun, and inspirational. In a long term effort to develop dynamic computer controlled surfaces, I began exploring fluid control (in this case, compressed air) as an alternative […]
