Secret Knock Description – My final project is a door lock that listens for your personalized knock. The lock uses an arduino board and a piezo speaker and will not unlock the door unless the specific pattern is used as a knock. Arduino Program – /* Detects patterns of knocks and triggers a motor to […]
This project shows how to send SMS text messages to a cheap scrolling LED display via an Android app and arduino with USB host shield. The project was originally inspired by a friend wanting to make a “sexting themed” costume, with a scrolling LED display of live texts sent from people at the party. We […]

This Instructable is about: building an automated photo booth. The total build cost was around $150 as I re-used a lot of the components and materials I already had in my garage – in addition to what I could salvage from scrap yards. Why? – I decided to build my own photo booth after trying […]
Introduction Microcontrollers like the Arduino were designed to facilitate the use of electronics for designers and DIY enthusiasts. The interface provides a great starting points for a variety of elecronic circuit designs. However, as the microcontroller is standardized, it is also limited in its use. That shows for example in the limited number of PWM […]
Web site: http://www.instructables.com/id/Human-Body-Infrared-Smoke-Temperature-Alarm-System/ Project Summary: The Human Body Infrared Smoke Temperature Alarm System works under the DC 5v voltage and uses the DH11 Temperature Module to detect the room temperature. When the module detects the temperature is higher than the maximum, the buzzer alarms and the red LED lights. When the MQ2 Smoke Sensor detects […]

When we first released our 3D printer, we tried to use some parts that were already available and tested, in full respect of the open source philosophy. In particular, we decided to use the electronic card Sanguinololu. The “open” firmware we chose, the Marlin firmware by Erik van der Zalm, solved the biggest part of […]
