I have a EL Sequencer and FTDI 5V breakout board. I have been have been unable to program it. All my attempts get some variation of "programmer is not responding".

I was using these instructions as a starting place. I soldered the 6 pinholes as indicated. I have connected everything. I am not sure if I should switch the FTDI jumper to 3.3V (it is currently at 5V). The pin in the EL Sequencer is labelled 5V, but the instructions also say "the EL Sequencer runs an ATmega328p at 8 MHz and 3.3V". Should I change the jumper to 3.3V?

I have downloaded the latest IDE from here. But there is no board option for the EL Sequencer. What board should I select?

Anything else I need to do to program the EL Sequencer?

Thank you,

  • is the FTDI board working correctly? – jsotola Dec 26 '18 at 19:58
  • I am not sure how to check. It was new when I purchased it. – Xyphon Dec 27 '18 at 22:05
  • just because it is new does not mean that it works ......... connect RX and TX together ..... plug the module into your computer .... open serial monitor, choose the correct com port ..... type something on the keyboard ..... you should see the characters on the screen .... you should also see the LEDs on the module flash – jsotola Dec 28 '18 at 5:40
  • Thank you for telling me how to test the FTDI. I did as you suggested and received the same characters that I typed. I also saw the LED on the FTDI flash. It appears the FTDI is working. Is there a similar way to check the EL Sequencer? – Xyphon Dec 29 '18 at 21:18
  • no there is not .... just connect everything together as before and try choosing Arduino Uno in the Arduino IDE – jsotola Dec 29 '18 at 21:31
