  • Could you please recheck the wiring, the driver getting hot may be due to incorrect wiring or heavy load usually. the code seems correct as far as I know. if you suspect low voltage go for a 9v battery and check the delay issue. Commented Aug 7, 2017 at 13:22
  • Show how you have things wired. The 2 seconds off sounds like the board is resetting and you're waiting through the bootloader. Commented Aug 7, 2017 at 15:48
  • Also what is the current draw of the motors? Do you have a part number or datasheet? The driver getting hot suggests that you're running too much current through it. These little drivers cannot route much current. Commented Aug 7, 2017 at 16:00
  • I add 9V battery and it go good, but after first back() function stop, and after 2 second back() again, but slowly. There is scheme: link Commented Aug 7, 2017 at 16:54
