Fish Robot

Fish Robot ProjectPrinciples of the Swimming Fish RobotWe can say that fish swim with pushing water away behind them, though fish swim by various methods. As the well-known categories for the swimming fish, a zoologist, C.M. Breder classified into the following three general categories based on length of a tail fin and strength of its oscillation...

Schematic Arduino Digital Thermometer

This Digital Thermometer based on famous Arduino board and LM35DZ as temperature sensor. The sensor component has three pins, +5V, ground and a variable voltage output to indicate the temperature. This simple project wired the sensor output straight to the Arduino's analogue input 0. As display, it use two line LCD (a Displaytech 162B).Tags...

Schematic AVR Project Wii Conductor

This AVR project is a simplified implementation of Wii-Music, utilizing a Nintendo Wii Remote (“Wiimote”) to play a gesture-based music game with the player as a virtual music conductor. The project exploited two of the Wiimote’s features: its wand-like shape and the embedded 3-D accelerometers. By interfacing between Microcontroller AVR...

Schematic AVR Electronic Combination Lock

CodeLock AVR is electronic combination lock based on AVR microcontroller AT90S2313 or ATtiny2313. User code is consisted of 1 to 8 digits. If the code is entered in the correct sequence, then after 1 second the relay and the electric striker (in the door) switch on for 1 second and then switch off again. User code can be changed via 3x4 matrix...

Schematic AVR Electronic Lock with Key Generic RFID

This is a generic 125KHz RFID tag reader and an electronic contactless lock. The project is based upon microcontroller AVR ATtiny2313 and generic 125KHz RFID. Here is the project work: the code of first tag that is read after chip programming, is stored in the micro Earom (non volatile) and it works as the "key". Every time that tag is read...

Schematic PICTalker - Low Cost PIC Speech Synthesizer

PICTalker is a low cost allophone-based system for synthesis speech. The system use PIC16F628 microcontroller as main processor. You need a PIC development system and programmer, and Microsoft QBasic to program the microcontroller and EEPROMs to build this poject.Speech quality is somewhat inferior to that from an SPO256 system. Most people...

Schematic Simple AVR USB Temperature Probe

This simple USB temperature probe uses the AVR USB library by Objective Development. The included ruby script reads the temperature and optionally logs it using RRDTool. The EasyLogger would send the data values over a keyboard interface. The project uses a custom device class and reads values using the ruby-usb library. The project primarily...
