Amateur trying to build a basic thing
January 22, 2020 - 9:35pm

Hi, I could really do with some guidance and help. I'm a complete amateur and have zero experience in electronics. I want to make something which would help my disabled son play a particular game. It seems simple enough.

I need two wireless buttons one for left hand and one for right hand. The left will subtract by 1 and the right add by 1. A running count then needs to relayed to a simple small screen or display, nothing fancy, just a small readout wil do.

Any ideas what parts I need to find and where do I start to work this out?

Thanks for your help

Hey Guy, you can do it using an Arduino by interfacing it with 433MHZ wireless module, as you want to make it wireless.The flow of the complete system will be, there will be two buttons connected to RF transmitter module.In the receiver side, this data will be received and just program it using Arduino to display the numbers in a 7 segment display or LCD as per your preference.Hope it helps!!!

RF module will work. Since you have zero experience what is you planning?
Are you looking for something that will do the job by jist connecting wires?

Thanks for all the helpful comments they have already set me in a direction. On more thought I think I can drop the wordless na dkeep the buttons and main display all wired together, hopefully make it more simple. Yeah I don't mind how it looks, just connecting wires is good of it will do it. But I guess as I will have to program something to tell it on button takes away one and the other adds one, is that correct? I guess I would do that programing though arduino? Also I think I will need a buzzer of sort when the count gets to certain numbers but I guess that's juts a case of programing though arduino?

OK sorry for another post. So if I drop the wireless module from what I gather all I would need to do is below, I have repeated what I need it to do as I ma not always very clear.

Need: two bottoms, one button adds 1, the other takes 1 away, so the user can press either one and then a running score needs to be kept on the display which also sets a buzzer or light off when the total reaches predetermined numbers.

Is it just a matter then of buying a arduino boards, two switches, battery and a display, hooking them all up and programing them through arduino? Sorry if I sound like a complete idiot on this, I most likely am.

Hey Guy, if you drop the wireless idea, then it is much simpler.just connect two buttons with an arduino and a LCD.Then program it to do your requirements.For power you can use a battery.Hope it helps!!!
