Gas sensors are employed in a wide range of applications in the fields of safety, health, instrumentation etc. Common examples are domestic/commercial alarms for explosive or toxic gases, or in automotive application as gas leakage detectors for LPG powered cars and exhausts detectors inside any fuel-powered truck/car. Such sensors, nowadays, are found also in [...]
Talking Elevator is a simple, low-cost and easy to install voice message solution for elevators. It can be set up and installed in minutes without the cost of modifications to elevator’s electrical systems and cabling. With very low power demands the system can work from batteries for about 1 to 3 months (depends on [...]
Teachers Timer is ATtiny13-based innovative and discrete timing device for assisting teachers and lecturers. Using cell phone style vibrations and a simple one-button interface the user can be alerted to the passage of time without staring at the clock. For lectures and presentations the device can also include a laser pointer that will gently [...]
The goal of the project is to build automatic home blinds system. The controller will open the blinds at first light and close them at sunset. If the sunlight becomes too excessive the blinds will partially close to protect the furnishings in the home. If the heat becomes too great the blinds will partially close [...]
The project has ability to measure temperature from up at 8 DS1820 digital temperature sensors all on the same one-wire bus and Log it to a PC using RS232. It can be used to measure temperature at range -55 to +125°C without calibration. This AVR AT90S2313-based project use only 3 wires for all the temperature [...]
The project goal is to build an electronic door lock based on Arduino and ID-20 RFID reader. This security system consists of 3 main parts, Arduino controller, RFID tags Reader and electric door lock. The RFID reader is located outside of the door and is separated from the controller on the inside so no one [...]
The SNAKY project goal is to build a robot moving around using the same crawling principle of a snake. This ‘fun robot’ is made with a set of thirteen articulated sections and the angle between each pairs of sections is driven by a servo motor (so twelve motors), simulating the muscles of the snake. Each [...]
