Hi, sorry for inconvenience. Yesterday I used mobile to create this topic, I could not find how to post code with mobile phone. Below is the full code. Please take a look at lines 175, 184 and 187 for the show( ) calling.
The circuit is simple as the picture. Even the logs show the correct for loop with number of leds, there is only 1 first led lighted up
