Bill details how a microwave oven heats food. He describes how the microwave vacuum tube, called a magnetron, generates radio frequencies that cause the water in food to rotate back and forth. He shows the standing wave inside the oven, and notes how you can measure the wavelength with melted cheese. He concludes by describing […]

DTMF is an abbreviation of Dual ToneMultiple Frequency. When you press a button in the telephone set keypad, aconnection is made that generates a resultant signal of two tones at the same time. These two tones are takenfrom a row frequency and a column frequency. Theresultant frequency signal is called “Dual ToneMultiple Frequency“. These tones are identical and

Hi friends, here is my experiment with i2c bus for interfacing serial EEPROM (24C256) and RTC (DS1307) using AVR microcontroller ATmega128. The circuit is also provided with an RS232 port for connecting with PC to send commands for reading/writing EEPROM or setting date/time in RTC (Click on images to enlarge them). Communication with PC is
