hey guys, looking for some code to display numbers 1 to 6 on 7 segment display. Thinking of polling the one of the pins connected to the switch and using an auto reload timer that counts from 249 to 249 as 1 to 6. Know what i want to do but need some help with the code?? thanks ....etc

final report file of digital dice using ic 555 in pdf

Playing with dice is an age old game. We all love to play with it too. Playing with dice needs us to pick up a dice and make sure that it is unbiased. Making a block as a dice and cutting it clearly to make sure that it is unbiased is all an old story. The dice becomes biased if the shape is not cut well. Also, the dice can become biased due to deformations. If it is a wooden die, it can deform due to dampness in the atmosphere or due to mechanical stress. To solve all these problems which ....etc

A countdown timer is a down counter that counts from a specified time to 00:00. It is used in many devices such as washing machine, televisions, microwave ovens, etc. This countdown timer has three states: the running state where it counts down, the pause state where it displays the paused time and the reset state to set the countdown. The countdown is displayed on a set of four seven segment displays using the 8051 microcontroller (AT89C51). A buzzer sounds when the countdown gets over. ....etc

digital dice using 8051 microcontroller at89c51

It is a project that builds microcontroller programming interest in new student and hobbies. This project is a very simple one that can easily be built by new students. It uses 7 LEDs, 8051 microcontroller and an optional 5V power supply regulator part. It s algorithm is also very simple.
1) Initially microcontroller displays 1 on LEDs display just like in real dice.
2) Then in main while loop it waits for switch attached to pin 0 of port 1 to be pressed.
3) Until switch remains pressed it gener ....etc

simple digital clock using 8051 microcontroller at89c51 pdf

Digital clock displays the time using numbers. This circuit is used in many applications like cars, railway stations, houses, offices, etc. in order to provide accurate time and date. In this type of applications, normally we use RTC (Real Time Clock) ICs to display the time and date accurately. This circuit displays the time on LCD. For this clock, we can set the time at any instant. Here the clock works in 24 hour mode and the RTC chip is configured by programming 8051 controller.
