G+_James Hughes Posted January 30, 2016 Share Posted January 30, 2016 I want to build an announcement board for my classroom. The idea is to use an old monitor and a raspberry pi. I am going to build a frame to hold everything and mount it to the wall. I want it to display a Web page that will have a calendar and other stuff. For controls I'm thinking three momentary contact buttons, forward, back, and enter. Would it be possible to put the website in a frame /program on the pi and map the buttons to the corresponding key commands? Link to comment Share on other sites More sharing options...

G+_James Hughes Posted January 31, 2016 Author Share Posted January 31, 2016 I I thought they were smart people on here not smart a$$€$. I'm looking for a suggestion for a program or something that will manage it that runs on a Raspberry Pi. If you have a serious answer I can help please reply otherwise keep your snarky comments to yourself. Link to comment Share on other sites More sharing options...
G+_Jeff Brand Posted January 31, 2016 Share Posted January 31, 2016 Look into gpio on the Pi. The pins can be used with those switches to emulate key inputs, run commands, and more. Adafruit has kits and tutorials that will help prototype the circuits and code you'll need. They also sell screens and enclosures that may be just what you need.

G+_Carlton Dodd Posted January 31, 2016 Share Posted January 31, 2016 James Hughes If you ask more specific questions, you will get more specific answers. I would think a teacher would understand this. If there is some part of the project you are having difficulty finding an answer for, I'm sure many would help. But, a broad, "How [do I do this project]?" will not get very good answers. Link to comment Share on other sites More sharing options...
G+_Jeff Brand Posted January 31, 2016 Share Posted January 31, 2016 I missed the dialog in the middle. Carlton was being unhelpful in the best of ways, with a little push out of the nest. Flap your wings and see if you can fly. Cheesy metaphors aside... James, while what you're asking for might exist exactly as you need it, that part is up to you to find. I would start with a customized kiosk image that would give you a minimal base OS that did little more than boot to a browser. Then I'd find a previously mentioned GPIO tutorial and install the relevant bits and make sure those too were loaded at boot time. At some point, you'll also have to work on the web page and likely learn some JS. Since I last looked up Pi kiosk images, the one low-cost image that I had used in a previous project seems to have been superceded by dozens of tutorials, likely using free alternatives. Start digging! (or flapping.. Darn mixed metaphors.) Link to comment Share on other sites More sharing options...
G+_James Hughes Posted January 31, 2016 Author Share Posted January 31, 2016 #Carlton Dodd if you bothered to read the question in the second paragraph I was not asking a broad question. My one word question was in response to a one word response. I'm learning this stuff by asking questions. I'm sorry they weren't detailed enough for you. #Jeff Brand Thanks for the reply (well, the second and third ones, lol) I'll check out the adafruit website. Now that I have a better idea of what I should be looking for I'll start flapping in that direction. Thanks for the help. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted January 31, 2016 Share Posted January 31, 2016 My first thought is to have Chromium or Firefox load on boot of the Pi then use the buttons attached to GPIO as keyboard inputs. The problem there is that it may take a bit to get your website to respond to the button inputs. I think there's something here about using GPIO buttons to emulate keyboard presses: https://learn.adafruit.com/retro-gaming-with-raspberry-pi/buttons Link to comment Share on other sites More sharing options...
