Hi. I hope this request is within forum rules. I couldnt spot anything that would make it "illegal" but apologise in advance if it is. I need some assistance with design of a circuit for a project I am building for a charity fair, to help do some fundraising. It is probably a simple request but any ideas for "jazzing it up" a bit would also be welcomed. (Bearing in mind I have a fairly basic skill set and for example do not wish to do any soldering.) Anyway - here is what I am trying to do: I have a board, A1 size. The LHS of the board is split into a grid of 49 squares, within each square is an object. Underneath the object is either a pin, or a 2mm socket connector. On the RHS of the board is a list of names of objects. next to each name is either a pin or connector. The challenge to the game participants is to correctly link (i.e. connect) an object within the grid to the name for that object. I see this being acheived by use of a cable where each end has either a plug-connector or a croc-clip which allows the pin/socket in the grid to be connected to the pin/socket by the Name. Having made the link, a switch of some sort is activated, and if the link is correct, a (green?) light comes on. This is the very basic requirement. It would also be nice if I had a solution where when the link is not correct, something else happened! e.g. A red light comes on or even better a buzzer that makes that awful noise like the Family-Fortunes "WRONG" sound woud be great! (Want to make it fun!). Anyway - I presume it is something I could run off a few AA or C batteries. All suggestions gratefully received. Now the tricky bit - I only have five days to build it. And need to source my components within the UK (e.g. Maplins?). I am fine with connecting wire to terminals so think it will be quicker for me to take that approach than trying to learn to solder within that time. I think all of the info required is above but please let me know ifyou need anything further. Thanks in advance for any help offered. Stormy!
