Real Time Clock PCF8583 Using AVR microcontroller Using Atmega

Description The PCF8583 is a clock/calendar circuit based on a 2048-bit static CMOS RAM organized as 256 words by 8 bits. Addresses and data are transferred serially via the two-line bidirectional I2C-bus. The built-in word address register is incremented automatically after each written or read data byte. Address pin A0 is used for programming the hardware address, allowing the …

ATTiny2313 Multi-mode LED Matrix Clock Using Atmega

This is a mutli-mode clock project based on attiny2313. it employs a 8×8 led matrix as display. with the limited resolution, this 12 hour clock shows time in 6 different modes. The circuit employs row and column multiplexing to drive the leds, one row at a time, this gives a 12.5% duty cycle when “sets” of leds (8 of them …
