//20240612 prj18 while loop use slide switch
//program use switchs control leds, array structure
//in working Lab use 1 slide(no bauce), hardware connect together in Simulation
//  software we write command to each 1 slide control 4 leds ledleft()
//   sw1 mean slide control 4 lcds function ledleft()
//important this program use command pinMode(pinsw[i], INPUT); Cannot use INPUT_PULLUP
//because wokwi has bug, We slove the problem by use R 100k connect to 3.3V and pin slide 
//normal hardware Simulation can use command pinMode(pinsw[i], INPUT_PULLUP); and No need
//to use R 100k connect to 3.3V and pin slide, as surely It work
