Hello!
I need to control 7 segment (3 digit) on webpage by textbox . :~
my condition
if i need to show "999" on 7 segment, I will insert "999" in textbox then i click button to send "999" to 7 segment and show current 7 segment number on webpage also.
now, I can set "999" to show no 7 segment by fix code but i can't create textbox an send "999" to 7 segment as my condition because i don't know how to ?
somebody can you help me, please
sorry about my English is not well (so bad) XD
This is some mycode
