I want to make a laser tag system and i was wondering how you would go about setting up the electronics that would do this: have a small lcd screen with number 10 on it, and every time the infrared receptor receives signal the number goes down by 1? (these would be the lives, and the signal would be the infrared beam from the opposing gun) Thanks not much experience working with micro controller and such
And got the following answer:
Are you talking about an LCD screen from something like a cellphone? If so, you are automatically going to be doing something complex. The simplest way to do this is to get yourself a CMOS 4510 up/down counter. Set up this chip to count DOWN in DECIMAL, and set it up with a RESET switch-button that will set it to go to 9. Then connect the chip's outputs to a 4511 7-segment LED driver, which will in turn be connected to a single-digit LED display. If you want it to go from 10 down to 0, you will need two 4510's rippled together, one for the ten's-place, and one for the one's-place (as well as a pair of 4511's driving both LED displays). To make it absolutely simple, you could use a single 4516 binary counter, set to count down and preset to decimal 10 (binary 1010), and feed its output to an LM3914 bar graph driver, and connect it to a 10-light LED bar graph (a row of LEDs in one case). As it counts down, the LED lights extinguish themselves until the count gets to 0 and all have gone out. I'm not sure what would happen if the count reached zero and you got shot again - it could roll over to 10 or 16, depending on which chip you are using for the counter, but I think it just stays at 0 - I don't have a data sheet(s) handy. Anyway, you can get all the parts you need (and data sheets) at Jameco: http://www.jameco.com/webapp/wcs/stores/servlet/StoreCatalogDisplay?langId=-1&storeId=10001&catalogId=10001 Here is a circuit that I found if you want to build a programmable 2-digit up/down counter (more complex design): http://members.shaw.ca/roma/up-down.html Here is a kit you can buy that is ready to assemble: http://www.apogeekits.com/counter_timer.htm
