FYI it is hard to find the high side current sense IC because the schematic label is not the manufacturer part number. ZXTC1009 datasheet http://www.diodes.com/datasheets/ZXCT1009.pdf . I believe is...

Can you power this with a 9v battery after its snapped apart?

As long as ‘this’ is the Arduino Pro Mini-variant part, yes. Check the schematic – there’s a voltage regulator on that sub-board that accepts up to 16VDC and gives the appropriate output voltage for...

I was planning on just soldering the leads directly to my PCB. Crazy how this is the same price as the holder w/o a JST connector. JST connectors by themselves are like a buck a piece. Maybe it’s a...

I just noticed they sold out super quickly – hopefully you got one. If not, they should be back in stock in a week (and backorder is available).

Yes!Make sure the cut is clean so there isn’t a short between the inner wire and outer one. And do be aware that you can get a slight shock from the exposed end; if this is a problem you might want to...

So theoretically this should work great with a couple of xBees, yes? I noticed the latency as you were moving the sliders and such. Have you tried higher baud rates and does that help reduce the...

There are no resistors in these (so you’ll need to add your own); they’re just plain LEDs with the cathode on one side and the anode on the other.

You can make the connection any way you like, around here we’ll generally put a female header on the FTDI board and a male header on the Pro Mini.

The sloppy cut is my fault. I was in a hurry to get the video posted. The LEDs work like they’re supposed to.

I don’t know if the supplier changed, but the plate is NOT Aluminum. A simply test with a magnet will verify…

Good observations! The latency is due to a number of factors, not least of which is my really inefficient code. I made it overly simple to understand and, in doing so, left it a little bloated. There’s...

hey, i was wondering if anyone has used this shield to control 8 DC motors ( 4.2A, 12-18V) or even 1 DC motor. If anyone has, could they possibly help me. Thanks.

Will there be a supplementary video or post about using the screens with a raspi? Also, are there any differences between the 3.2 and 4.3" screens other than size?

Love the idea, love the fact that IDE is fairly flexible, love included controls, hate the fact that amount of controls actually very minimal, would be great to have some standard controls like check...

I think you’re underestimating the amount of effort just slapping things together would be if you want to come up with something so easy to use. Yes, something like this could be made cheaply using...

What ohm resistor would I need to step down 9v to 3v? Or do I need some sort of current limiter to prevent spikes – I’m new to arduino and this is for a project.
