So I decided to make new post because I'm just at the point where I need help anyway whether it be changing the project and materials. I don't think my way is going to be possible. What I'm trying to do is make a bingo board for a disabled client who has trouble putting chips on a bingo card. I thought I could make a bingo board using arduino and having 10 light sensors and 10 lasers pointing to each sensor. So it would be a 5 by 5 grid where you got 5 lasers pointing to 5 sensors up and down and 5 lasers pointing to 5 sensors from left and right. I was getting somewhere but there just keeps on being problems with the lasers and the sensors and the cage to make the bingo board. I'm wondering if you any of you guys have a better idea on how to approach this. My teacher keeps telling me this is simple but I'm not seeing this. If someone could just leave a reply or input that would make my day. I'm a senior in high school already accepted to college and I'm stressing out to the max. PLEASE SOMEONE HELP ME

My teacher keeps telling me this is simple but I'm not seeing this.
Your teacher is paid to help you when you get stuck on a project. Consider changing the project to something simpler if needed. Often students select projects that are beyond their current capabilities. Starting new post on the same issues in previous post may not get you more help.
How about a simple 5x5 keypad, 25 discrete buttons so you can space them out some if needed, read buttons presses with Keypad.h library?
Have an adjacent LED to show which had been pressed.
If want to get carried away, use buttons with built in LEDs that you turn as buttons are pressed, have a Clear button to turn them all off when game is over.
Cards have random # assigned to each square? So maybe a small 2-digit display at each location as well so the "card" can be mixed up.
Did anyone ever ask you to make your subject line to match the topic ?
many of the people who would help do not respond to posts that do not have proper subject lines.
the thought is that if you cannot convey the minimal information properly it makes it hard to offer advise.
I like the idea of having a 5x5 keypad and a 5x5 LED light box.
you put the card on top, when you press a key, the light illuminates the square.
I cannot figure how the lasers would actually input. if you move your hand over the board, the shadow would be huge.
if that is the display, then how does crossing lasers work ?
the instructions are very confusing.
one little bit of knowledge I have learned over the years is to re-read the question and make sure you understand every possible step. if you cannot understand the question, you cannot complete the task.
Your project objective is somewhat vague. You need to post your Project Objective in an organize format.
List the objectives of the project.
Be specific. If you talk about some hardware, post links to the vendor's website or a datasheet.
How is this Thread different from your previous one?
Is there any reason why I should not ask the Moderator to merge them.
Four pages on the other Thread don't seem to have made any useful progress.
@minypablo, I don't intend to be unkind, but I can't help feeling you are completely out of your depth. You seem to have some vague idea in mind without the least idea of how to implement it.
If this really is a school project, discuss it with your teacher and find something that you are capable of implementing.

This doesn't tell us anything. If you want help, give us a proper SITREP (SITUATION REPORT)
List one by one in outline fashion , EXACTLY what you have REALLY done. Explain EXACTLY how you did it. Draw a schematic
with pen and paper and take a photo with a cell phone and post it. Post your entire code. (using the "#" code tags toolbutton.
When you have done ALL that, THEN , we will talk about how we can help you. So far all you have provided is the usual sob story we get from every single newbie on every single new post. Once in a while , we get like a college professor or scientist who knows how to present his project in a half way decent organized fashion without the groveling.

I read the directions and I could not create something useful from them.
if the client a parapalegic and needs to use eye movement ?
is the device to project dots on the page ?
will they have more than one card ?
the information appears to be incomplete and confusing.
what is a question in the back of my mind is the use of the word "client"
to me that means paying.
also, the simple fact the posted did not bother to title the thread with any useful information is a bit of an insult. it eliminates the ease of which others can use this thread.

The post title should have reflected something to this effect.

@Dave, I'm not sure why you quoted me?
I think "client" is the polite modern word for what used to be called a "patient"

There's that politically correct BS again !. So invalid is no longer acceptable ?
Ok I truly am sorry about the scrappy desparate post. I was not myself. It was all the stress building up inside of me and exploding. In a couple minutes I'll put out a better explanation of my project and some diagrams and hope some of you guys can give me an idea of how to construct it and what the best method is. I was honestly looking to see if there's a touch sensitive grid out there but couldn't find any and I think big buttons were too expensive. Once again I am truly sorry for the horrendous post. Also my teacher will barely help me. I feel like a project like this is meant for college not high school where I havnt even fully learned the language or much in electronics
How are your soldering skills?
Wire up 25 buttons in a matrix like this.
Wire up 25 LEDs to a MAX7219, turn on an LED when a button is pressed.
I have a board that will make the LED wiring easy for you.
high school ?
my friend, I think the best thing to do is to post the instructions.
I quoted Robin2 "I can't help feeling you are completely out of your depth." and the reason is that I cannot follow the instructions to offer a simple solution. we are on page 3 of the second thread and I believe no one knows the actual project.
I think there is something lost in the translation from the teacher to you and then from you to us.
I still do not understand what is to be used as a sensor (button?) and what is used to indicate the square on the bingo card.
you say laser. do you mean LED ?
you could use 5 buttons.
one for each column.
press the first one once and it is the first row
press it again and it is the second row and so on.
if you have 25 LED lights, one for each square, then you need to be able to control 24 outputs.
this can be done with 3 shift registers and no need to bother with the center square.
as for the buttons, you might need an extra one.
press the column button until the light moved down to the correct square. then press the send button (the extra one) to lock it in.

I totally agree with you here. Make the title useful.
And as a suggestion, lasers? Stick to a more basic design, then escalate.
Use a membrane keypad.

Did your teacher specifically assign you this project, or did you chose this project on your own? This is important as to the teachers responsibility in helping with the project. If the teacher assigned this specific project, then the teacher should have taught the needed knowledge/material required for completion of the project. If you came up with this project, you may have shot yourself in the foot. You may want to rethink how the bingo card is designed. What physical capability to interact with objects/environment does the disabled person have? You might have an LED in each card square that blink sequentially, and when the square LED blinks, the person does something to tell the arduino that that LED should remain lit. Probably many ways to get the basic job done.
not sure how much latitude you have, but Crossroads offered buttons as inputs and led's as outputs.
A) you can use a 5x5 button array,
B) or 1 button that you press 25 times.
C) you could use 2 buttons, over and down and make the person press them to light the desired square.
D) 6 butttons, either one per pin (easier) or use a resistor to make a voltage divider for AI (not much harder)
using the 2 buttons or 6 buttons would need you to program them to step down through each row.
for 24 buttons you would need either a shift register to input the button data or use a voltage dividing network and connect to the analog pins.
24 LED's
3 shift registers
caps
the 5x5 LED's light up by the 595 shift register.
you can find the sketches to do most of this in the menus of the arduino software.
