Troubleshooting

Problem....................... Solution

  1. When external power using arduino on/not turn on: Try to use 5v adapter connect to 5v+ arduino or (7-12) V connect arduino Vcc pin.
  2. Wnen DF player volume (25-30) set its not working; Try to use max 20, if use only 1 power supply
  3. USB connect work fine, when use external power supply not working.

Make sure power supply Vcc- GND connect Properly and try to 3/4-time plug /unplug power cord

4.When led strip brightness 200+ set arduino stuck; try to set led brightness max 200, when only 1 power supply
