Re: Permanent arduino connection

For one-off projects, I generally use a proto-shield of some type, like https://www.sparkfun.com/products/13820. The tension from all of the pins together is pretty secure. Then just solder whatever connection you need directly to the board.

Re: Shift Register + Potentiometer

The shift register is probably not going to work the way you want it to. You could use something like https://www.sparkfun.com/products/10615.

Re: Motor control

If you don't want to use the connector the power supply comes with, cut it off. Then strip the ends of the wires and insert them in the screw terminals.

Re: Forum search not working

I can't fix the forum search, but I do have a tip that might help. Google supports a search operator that allows you to specify a site. For example, if you use

Code: Select all

site:forum.sparkfun.com your search terms here
you'll get results for your search terms that are restricted just to pages from this forum.

Re: Addressable LEDs 12999 RGB color issue

This note is in the strandtest example code: // Parameter 1 = number of pixels in strip // Parameter 2 = Arduino pin number (most are valid) // Parameter 3 = pixel type flags, add together as needed: // NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs) // NEO_KHZ400 400 KHz (classi...

Re: Measurement card PCB

Usually, you buy parts that fit your needs rather than buying parts that fit pre-existing Eagle footprints. If the footprint doesn't exist, it's fairly easy to create a custom one. Sparkfun has a tutorial at https://learn.sparkfun.com/tutorials/making-custom-footprints-in-eagle that explains how to ...

Re: Review my PCB

The Chinese PCB manufacturers are getting more creative in their techniques, but their continued insistence on spamming every electronics forum with ads for their services are tiresome.

Re: Addressable RGB - COM-12877

You can also feed voltage to both ends. This will be more effective with heavier gauge wire. See https://learn.adafruit.com/adafruit-neopixel-uberguide/powering-neopixels for a more detailed explanation, particularly this section: https://learn.adafruit.com/adafruit-neopixel-uberguide/powering-neopi...

Re: Addressable RGB - COM-12877

Each of the LEDs retransmits the signal, so distance from first to last isn't necessarily the problem for the signal. It sounds like your issue is voltage drop in the cabling. Check the voltage at the far end. Insufficient voltage will cause color problems.

Re: RF Remote to Receiver >Arduino for Scoreboard

How is the remote connected to the Arduino? If there is any kind of mechanical switching in your remote receiver (like a relay), you'll need to debounce the Arduino inputs.
