IR Remote Controlled Scoreboard :: Member Project
Arduino and Bean Bag Baseball? Yes – match made in heaven!
PEA customer, John Wren, built an IR Remote controlled Arduino powered scoreboard for his senior community bean bag baseball team. It includes tons of NEO pixels and looks great. Learn more about his project below!
Why did you build an Arduino scoreboard?
I live in a senior community and we play bean bag baseball. We keep score on a whiteboard. I thought it would be nice to have a more robust way of keeping score and I thought I might be able to sell some of the scoreboards if it works out the way I plan.
I recently retired from the industrial automation field and was bored and looking for a project, so I started to learn Arduino coding.
How does your project work?
The brains of the scoreboard uses an Arduino Mega. I selected the Mega because originally I was going to use buttons to control the score board.
Currently the scoreboard is controlled by a GE IR remote using NEC codes. The scoreboard has a score for each inning both for home team and visiting team and a total at the end.
The scores are 7 segment displays using neopixels driven from a single output pin from the Arduino.
What was your biggest struggle as you worked through this project?
I am fairly new to micro-controllers, my background is PLCs and HMIs my thought process didn’t match that of the infinite loop of the Arduino. I was able to learn about hardware interrupts (pin 2 interrupt 0 ) and switch case. My current code does not use the loop.
I found that a loop was necessary to make the compiler happy so the loop is there but empty. I have coded in many different languages in the past. When I went to school we programmed in machine language. C++ is new to me and I had a steep learning curve. some examples =vs==, missing{} and ;.
It has been a challenging but fun process!
The project is not yet finished but is coming out close to my original concept. So far the only major change is the interface. Using the IR remote as opposed to buttons.
Was the training at Programming Electronics Academy able to help you build your skill?
Yes!! I truly enjoy the presentation style. I always had questions after the lessons and tested alternate ways of the exercises.

Arduino Code:
/* Program written by John wren (Wrengineering) 6/29/2020 This is designed to control a 6 Inning Beanbag baseball scoreboard via IR remote control using a Pure Control universal remotemdlPC 100 and RCA code 1033 remote uses 32 bits in 2 groups of 16 in each group of 16 the lower group of 8 is the inverse of the previous 8 so i utlized loByte to just use the value of the remote button that was pressed The first 16 bits identify the contrller and the second contain the code for the button presed this is sent in as a HEX value I converted lowByte to a BIN and used it to compare for Switch Case It will keep track of strikes, outs, men on base, runs/Inning and toal score Utilizes Interupt 0 on Pin 2 to decode IR remote signals Uses RGB led strips configured as seven segment displays for runs and total score Also uses LED pixels for strikes,outs and men on base Changed Seven_Segment_Pixel.h to match the order of segments on my display, in order tp make wiring simpler Progress as of 7/7/2020 strike increment and decrement. outs increment and decrement. Innings increment and decrement. Able to keep individual score based on Inning number Need to add score decrement. Have only tested with 2 7 seven secment LEDs (need to solder) with 16 7 segmet displays all set to the number 8 with a single color at full brightness the FLA would be 5.6 20mA * (21 LEds per secment * 16 total Sements) the dual Power supply has 6A at 5 volts and 3A at 12 volts at game start all scores set to zero FLa 5.28 I will lower the intensity and that should lower the current draw. Measure current with all scores This program will use a IR remote to control Strikes, Outs,Score, at bat team and inning. The operator will be able to increment and decrement each value witht the remote. (see remote diagram for button info) Currently using an Arduino but may switch to ESP 32 to add vioce and speed ***********************************TO DO NOTES********************************** This is where I kept notes of what need to be completed or fixed need to clear outs and strikes whith inning + or - */ //***************************************************************************************** #include <IRremote.h> #include <Adafruit_NeoPixel.h> #include <Seven_Segment_Pixel.h> //define pixel strip peramaters #define PIN 36 #define NUMPIXELS 112 #define DIGITS 16 #define PIXPERSEG 1 #define NUMDELIMS 0 #define PIXPERDELIM 0 #define PINSO 35//STRIKE AND OUT PIXELS #define NUMPIXELSSO 11//STRIKE, OUTS AND ON BASE PIXELS //Score display 7 segment digits Seven_Segment_Pixel display1 = Seven_Segment_Pixel(DIGITS, PIXPERSEG, NUMDELIMS, PIXPERDELIM, NUMPIXELS, PIN, NEO_BRG + NEO_KHZ800);
