ScoreBoard

by appletreeauto on Sun Jun 16, 2019 5:38 pm

Hello we are building a 7 segment scoreboard with 5 digits and 2 dots. I watched your video on it and would like to purchase a "kit" if possible for the circuits. We already have the display board built but will need everything else. Is that something you can put together? Also they are using a M0 pro and it looked like that was discontinued. Any alternatives for that?

Thank you
Chad

Can you post a link to the video?

We do not have a kit but there is a "featured products" section in the tutorial that lists the parts used.

I seen that and made a list off it but the Arduino that they are using (M0 Pro) seems to be NLA. If thats the case do you have a substitute for that

We have several M0 and M4 boards that would work.

Thank. the video is using 74AHCT125 quad channel level shifters but it looks like it will only handle 4 channels. Is that 4 channels each? I will have 5 digits on each scoreboard in a
88.8.88 arrangement.

didn't know if it was better to run the Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0 and 8-channel Bi-directional Logic Level Converter - TXB0108 but it says it doesn't have a strong output. Will the 74AHCT125 2 per board run 5 seperate digits?

Does the feather control everything? Or do I still need to get another controller

Very sorry for all the questions. I have about 600 so far in my cart. Pretty familiar with electronics and I am a mentor for our highschool robotics team but have never used these components before. Your website is great and I will make sure my son gets on and explores it.

I have checked out and paid and just purchased all the stuff to go both ways. I will use it on something but still would like recommendation on which way to go. If I use the 74AHCT125 do I need a different controller then the feather m0?

So I did the build a little different but overall the same outcome. Made a aluminum housing and recessed 1 inch foam inside that we water jetted the segments out of. Also a layer of powedercoated black aluminum for the face. In between the aluminum and foam is a thin acrylic material to act as a diffuser and then a final clear acrylic for the face. Made it bigger. 24 inch tall numbers will 11 leds per segment. My question is now that it is to this point I may need some guidance on how to accomplish the real job. These are drag race score boards and each lane will get one. The computer system will send the et and mph to these boards. Each board would probably need to be networked with a static ip so each lane would get their own data. I need a way to get that data into the arduino uno and up onto these boards. Looking for the hardware to make it happen and coding help. Any direction would be appreciated

Heck yes, that's looking amazing!

Sorry, I didn't see the earlier posts, let me know if you have questions still about any hardware or software.

BTW, one thing I did in code was remove all the print statements which were slowing things down.

Not sure which board you went with -- if you're using an Arduino Uno, you may want to look at using a Metro Express M4 (same form factor as the Arduino Uno) which is a much faster board.

John, thank you. I looked into doing the acrylic layer route but was getting very high prices locally. We have a CNC plasma but I have a friend with a water jet so we used aluminum and foam to seperate segments.

I used the UNO but would take you up on the suggestion. I modified the code to run 11 led's per segment. This is my first Arduino product although I am familiar with a few platforms. We have done many First Robotics robots over the last 6 years.

This is for a racetrack and the racers times are displayed on the board after their run (drag racing) the portatree timing system will output onto a 485 serial port and will send a signal to both the left hand and right hand lanes boards to display data. I am looking for some input on how to take that data from the portatree system and seperate it maybe by IP address and send it to each board and display the data. I was thinking some of the serial print commands may work but not sure. Any suggestions would be great and thank you for the GREAT tutorial. Very easy to follow.

Very cool, I'd love to see any in-progress photos of the build.

A good place to also post about getting your serial data filtered and sent to the two boards is our Discord server. http://adafru.it/discord The #help-with-projects channel would be a good place to ask.

And thank you kindly, I'm so glad to hear the tutorial was helpful!
