I wanted to make an easy and secure way to enter my garage. RFID was the best way to unlock my door, even with my hands full I can unlock the door and push it open! I built a simple circuit with a basic ATMega 168 Arduino chip and a ID-20 RFID reader to control …
NOTE: This Instructable is currently incomplete. I will finish it before September 19. I started this project after seeing Nick Johnson’s Turing Alarm clock. I found that the PIC chip he used was a little too advanced for me, so I decided to use the Arduino microcontroller. The original project by Nick Johnson can be …
This is a instructable for a very simple Arduino controlled electric lock. The key idea here is to be very simple as this was more of a proof of concept prototype type of thing. The Arduino is used as a switch to control the lock itself, and is set to interface with a Computer. The …
I’ve just completed my second Arduino project, a sound level detector which sets off an “alarm” when there’s the sound level is to high for too long. I built it for use in a school that wants to provide visual feedback to students when they are being too loud. The “alarm” is a string of …
The Arduino RFID lock How does it work? The Arduino RFID lock is a lock that can be opened easily, but is secure. The lock works with a server database that can register card codes. On the door there is a RFID reader connected to the lock. If the RFID reader reads a registered card …
I used: an Arduino Uno a Parallax PIR Motion Sensor and a Seeed Studio SD Card Shield Arduino, shield, sd card, logging shield, storage, logger Check out This instructable on PIRs in case you didn’t know what it is: http://www.instructables.com/id/PIR-Motion-Sensor-Tutorial/ Step 1: Connect your PIR Sensor Hook up the PIR Sensor Ground pin to Ground VCC pin to …
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 the SECRET SWITCH? …

*NOTE* THIS PROJECT IS DONE BY A GROUP OF STUDENTS FROM SINGAPORE POLYTECHNIC. Concept: Trigger gun when laser is blocked by intruding object. Note: Tilting is included for expandability but not used in this project. Skill Level: Basic soldering and basic metal works Things You Need: Toy Gun(Any will do, preferably a semi-auto) Continuous Rotation …

Hi guys! So for my electronics class this year we were tasked with creating some kind of electronic gadget in order to demonstrate what we learned over the semester. Being a car-loving type of guy, I decided to get a cheap RC car and see in what ways I could hack it using an Arduino …
As the nights gradually lengthened in autumn 2011, I discovered the joys of Arduino and thought that it would be a great way to implement something that I have wanted for a long while – a gentle way to wake up on a winter’s morning. Sadly, it has taken me over a year to find …
