Many thanks
I have a text file stored in sd memory as follows, it consists of three columns
0'10, 0
10, 0, 0
0, 0, 10
0, 0, 0
10, 0, 0
..
I have three LEDs connected to three terminals (pins) of the Arduino, for example 7, 8, 9

How do I get a code that enables the Arduino UNO to read the text file and convert each number 10 to 5 volts on one of the three pins
Thus, it will light three LEDs sequentially according to the data stored in the SD card memory. Thank you very much
