#151645 - Basic Microcontroller Timer |
Hi,
I am very, very new to this topic but I have been recommended to your site and have found some great tutorials, thank you. But I need to know if I am in the right place and aren't in too deep. Here is my problem: I require a very simple microcontroller to count up, in seconds, the amount of time the power is connected. Hopefully a watch battery will be enough. I would like it to display on 2 X 7 segment LED's and the whole product should be about the size of an egg. When the power disconnects I would like it to reset back to zero. Either that or just before it begins to count up. After reading about microcontrollers I thought they might be capable of doing something else, which would be the perfect situation: Once the switch has been flicked, can the LED's hold the last time for a few minutes? Or until a switch is flicked on again at which point it would reset and begin counting up again. How on earth can I make something that does this? Thanks for the assistance guys!! |
