Ask the Applications Engineer 1-Multi Troubles - AN-354 Analog Devices
Application Notes.....[App Note] Addresses problems often encountered with LOG
Circuits, Time Division Analog Multiplexing, and ADC Power Strobing
Audio/Video Distribution Amplifier - With the amount of equipment in home
entertainment centers today the need to be able to vary the gain of the audio or video
signal is needed. I found this particular circuit helpful when used in conjunction
with the Universal Descrambler and a Stabilizer circuit I built for making copies of
video tapes.....(electronic schematic / circuit added 05/05/05)
AVR 2x16 LCD & 4x4 keypad driver - A very simple circuit to experiment with
AT90S2313, 2x16 LCD display and 4x4 keypad. The clock based on 4 MHz crystal, but you
can use anyone crystal between 1-4 MHz. The keys with the name "A", "B"....."F" are
typed to the LCD with numbers 10-16. Because the AVR have only 15 I/O pins we are
working the LCD display with 4-bit databus. The 4 resistors (10K) are to protect the
AVR from the shortcuts as the coloumn of the keypad is change.....(circuits added

AVR Dotmatrix - avrDotmatrix, Is a 5x7 LED Matrix Display controlled by a
ATMega8 to display scrolling text, time or temperatures. The pattern is generated with
multiplexing the 5 matrix columns and setting the correct row bits. This
projects is still in development and i'm gonna add a temperature sensor
(LM75).....(circuit added 02/09)
