Hi I am currently teaching a class on electronics and have run into an obstacle. I have created a program for my Arduino uno to control a DIY scoreboard we made using 60 neopixles. The problem is we are currently using the BLE101 app and the UI is ugly and not user friendly. I was wondering if anyone could help give me some tips on how to convert this code over to Blynk Bluetooth. Would help me and my class out greatly. Below is the code we are using.

#include <Adafruit_NeoPixel.h>
