I am wanting to learn how to design and build digital led 7-segment displays. I wish to eventually incorporate them into my incubator thermostat design. I also wish to incorporate a humidity display as well. I learned how to make thermostats from ordering a kit and studying it to see how everything worked. I learn best by doing it this way. So what i need help with is if someone knows where i can order a 7-segment digital led display kit that will teach me how to do what i need, it's got to be a simple one though. not a lcd display (i don't like thoughs) please leave me a link or worst case, maybe a easy read link on designing a display for thermostats. Thanks.
