Category: Microcontroller Circuits / AVR Microcontroller This circuit is also crossed to: LCD circuits Views: 1146 Rank: 0 Its a digial clock which make use of AT89C4051 to work as a Real time clock. Port 1 of the controller (AT89C4051) is used as the data lines for the LCD (starting from pin 7- pin14 of LCD). As you can see there is not much change in the hardware except the LCD, here i am using a 20 x 4 lines LCD display.In figure 3 as you can see the digits are bigger than the normal size. For this purpose i`m maiking use of the CGRAM of the LCD, which gives the flexibility to the user to define user defined characters. so to create a character we first need to get visit page.

Related circuits Interfacing DRAM M5M44800 Memory with AVR AT90S8515 Is it possible to use DRAM with microcontroller AVR? Yes, it is possible. Jesperh has proved it. He hooked up a DRAM to a small processor (in this case an Microcontroller Atmel 8515), and handle the RAS/CAS sequencing and refresh in software. The type of DRAM is Hitatchi M5M44800, a 512k*8 DRAM!.... CREATING A SIMPLE FAN CONTROLLER An 8-pin Atmel ATtiny45 microcontroller uses one of its analog-to-digital pins to measure the voltage divided between a 4700 ohm fixed resistor in series with a BC Components 2322 640 66103 NTC 10 kilohm thermistor (Digi-Key BC1482 $0.68). The thermistor changes resistance in a predictable way... LED Countdown Timer with AT89C2051 A simple count-down LED timer that counts in minutes and seconds. Three buttons below the LED provide control of the unit, allowing you set the desired countdown time in minutes and seconds and a start/stop button. Completion of the countdown is indicated by an alarm that starts when the... Its a digial clock which make use of AT89C4051 to work as a Real time clock.

Auto plant Irrigation AT89C2051 The Project presented here waters your plants regularly when you are out for vocation. The circuit comprises sensor parts built using op-amp IC LM324. Op-amps are configured here as a comparator. Two stiff copper wires are inserted in the soil to sense the whether the Soil is wet or dry. Programable Board with 32K RAM While there is a list of features that I would like to add (32k EEPROM support, line numbers to 65,535, more stack space, strings, arrays, 16 bit variables and arithmatic, possibly named variables and REM statements for starters), I have not been able to dedicate much time to this project. You... The ATMEL, with family AVR, was consolidated in the field of microcontrollers. The microcontrollers are, providing fast core and a variety of peripherals. These features continue to occupy the attention of engineers and earn their preference. The developer will see, it accepts all models of the... Solar tracking System with AT89C2051 This is a power generating method from sunlight.This method of power generation is simple and is taken from natural resource. This need only maximum sunlight to generate power. This project helps for power generation by setting the equipment to get maximum sunlight automatically. This system is...
