如题。连线: 程序: [mw_shl_code=cpp,false]int brightMAX=63; int brightness=0; int brightFlag=-1; int ledOut=3; void setup() { } void loop() { if(brightness==brightMAX || brightness==0) { brightFlag=-brightFlag; } brightness+=brightFlag; analogWrite(ledOut, brightness); if(brightness==0 || brightness==brightMAX) { delay(200); } else { delay(10); } }[/mw_shl_code] 效果: |
