Re: M5451 and Arduino Nano v3

[G. Andrew Stone]

Hmm... your physical setup looks good (as far as I can see).  But please make sure you are getting 5v into the chip.  Try the code here: http://effluviaofascatteredmind.blogspot.com/2009/02/arduino-and-m5451-control-35-leds.html.  While the sketch is running, put a meter on the "clock" and "data" lines, you should see something in between 0 and 5v because the nano is toggling the lines.  Also, I'd recommend installing a few of the LEDs backwards -- just in case what you think is correct is actually incorrect!

Cheers!

Hello Andrew,

Thank you for fast replay. Please find attached prototype picture and PDE.

Description:

Arduino Nano v3 328

M5451 pin1 -> ground

M5451 pin19 -> 1k resistor -> 5v

M5451 pin20 -> 5v

M5451 pin21 -> Arduino pin2

M5451 pin22 -> Arduino pin3

We are tryed to turn on pin 17, 16 and 14. But still unsucssesfully.

If you are can to provide us simple code to turn on few pins, your help will be appreciated!!

Hello,

May be you are have simple code to turn on 1 or 2 leds? Still stuck to get it working. Here is Arduino Nano v3 and M5451 single chip.

CLK and DATA connected to pin6 and pin7. pin19 from M5451 connected to 5v via 1k res.

Please advise...
