The goal of project is to helps people develop the musical skills of perfect pitch and relative pitch. Push buttons allow the user to navigate a graphical user interface (GUI) on a liquid crystal display (LCD). In perfect pitch training mode, a note is played and the user tries to identify the note on an animated keyboard. In relative pitch training mode, an interval is played, and the user selects the correct interval name from a list of possible intervals.The project featured a MIDI input into the microcontroller for users ...

This VHF TV TRANSMITTER can be used to transmit movies from your PC to your living room, run a college TV station, hotel cable system info pages, re-transmit the TV program you've never been able to receive in your valley, cover rural areas of Africa with TV signal from satellite stations and other system that needs own TV broadcast studio.The TV Transmitter gives output power up to 3W and coverage range from several meters up to about 5 km, depending on antenna type used on transmitting and receiving side. High-gain ...

IR protocol analyzer is universal software for automatic decoding infrared remote control protocol packets. To capture infrared signal from a remote control, it uses microphone input of a soundcard. The hardware you need to start decoding is minimalistic and easy to build, just plug a phototransistor to input of your soundcard.This Delphi-based software processes InfraRed signal from a remote control and compares it with its own database of known protocols. When a match is found, packet is decoded and the software will display protocol name, description, decoded data and graph ...

This project shows you how to connect inexpensive calipers, micrometers and height gauges to PC through serial RS-232 interface and see the result using PC software. Its main part consists of minimal PIC to RS-232 interface, +5V/-1.5V power from serial port, and 1.5V to 5V logic level conversion. "The connector on the measuring instrument will have 4 pins, and the owner's manual will typically describe the output as 24 bit 90 kHz synchronous," said Kevin Timmerman, project designer.The caliper sends a burst of data approximately three times each second. Each ...
