Re: Making stand-alone USB buttons/switches/etc. ?

Completely confused by your last post. Here's code and link to hardware:
https://learn.adafruit.com/trinket-usb-keyboard/code

Buttons, switches, dials, etc are trivially easy to find. If you're actually seeking someone to build this for you, PM me.

Re: Making stand-alone USB buttons/switches/etc. ?

Prohibitively expensive depends on your budget and quantity you want to build, so unless we know that, we don't know what to recommend. Up to a certain volume, it costs less to use an off the shelf Arduino board than to spin your own. Remember that these guys are building thousands of Arduino clones...

Re: Ethernet UDP to serial display

The graphic LCDs take up a lot more Arduino pins. I honestly don't like them very much and I don't know if you'll be able to find one larger enough to give you that digit size. Whenever I've needed a larger display I always went to the Raspberry Pi because then I can use a 7" or large HDMI display. ...

Re: Pressing any one button clears any other that was on.

What is your reason for trying to avoid code? The solution will be far simpler that way.

Re: Need a Small 5v Power Supply

No, Please dont.
The LM7805 will drop 7V to do that, all the while passing whatever current your LEDs need. There will be a spectacular waste of battery power!
Not to mention that no one mentioned 12V in this thread.

Re: 20x4 SerLCD: is there a cursor?

The Arduino LCD libraries have a setCursor function. It works the same on all display types I've seen.

Re: Attach Standard 7 Segment LED to Large Digital Driver

The large digit driver is designed to be "cascaded" so you only need the data and clock pins.

Re: Ethernet UDP to serial display

Awesome! I had someone contact me a year ago to do bridge data from a Rice Lake Scale to another device, but then they just ghosted me. Hate when that happens.

Did you resolve the UDP problem? UDP can be a pain to work with sometimes.

Re: Hello - is this the right forum for me?

An Arduino can certainly do this. The additional hardware needed will depend on the type of sensor and motor you are using. You can continue to post here for help to continue a DIY project. If you need more specialized consultation, PM me. I offer construction services for small projects and I've sh...

Re: Ethernet UDP to serial display

I meant that you'd have an Arduino between the Moxa and the display to control the formatting if necessary.
If you can alter the data anywhere along the chain, I'm sure that will provide the format needed.

Re: Ethernet UDP to serial display

Can you program the Moxa? You may have to do some format conversion so the data displays how you like. If not, you can use an Arduino and a regular display and program the arduino to e.g., reposition to the start of screen on each update. Really cool would be to build it with those 6" displays so yo...

Re: Big easy driver fries when stepper mecanically stucks

My guess is that the driver is marginal for that size stepper and at speed, the current isn't high enough for long enough to cause a heating problem. But at idle with holding current on, it dissipates too much power
