Hello. I`m struck with my learning project. On Blynk i have slider, witch is showing current value on Nextion display. Then i decided, would be nice to have an option to change this value from Nextion display as well by using two buttons ( + and - ). But i cannot think of proper way to do that. Should i keep the value on Nextion, Arduino or Blynk virtual pin? Also, how could i update slider on phones screen? Happy with any suggestion or help, thank you.
Solved. Taking value from slider, writing it to Nextion, then in loop writing value from Nextion to virtual pins. Working well. Thank you.
