@byron Sorry, with my first GPS bot (2010/2011) I did not have a camera on a phone. I was using a laptop and a wifi router on the bot. I had a socke...

@ruplicator I myself would not monitor a battery like this. A good one should run for a long time.

You will want to use a voltage divider to read the battery voltage via an analog pin. Google "Reading voltage from battery voltage divider"

The connector cam on the board. I just added the cable and a rubber-ducky antenna.

I do the buy extra thing as well :) I would assume it would work with at least some USB devices. I would give them a try. It does have Wifi built-in...

@spyder Thanks! I have my Linkkit on a Naan board. One USB is power only and the other is host. both or OTG ports. You can find them on ebay now...

I have these Prema-PCB's that you can have made at any PCB maker: All you need to do is get the Gerber zip file of the one you want and upload to the...

Hi @codecage, Did you ever get this? I am just getting a lot of stuff from April and early May now. I received a Seeedstudio package just today fro...

With LEDs, I typically add a resistor that I like for the brightness. For IR, I would use the datasheet recommendation though. For small bursts that h...

@ve1dx Very nice. It is nice to be able to make your own designs! I have been soldering for a long time and am just starting to use SMD more. I...

I never could get the doc's for the is500 to load :(. With Modbus, you are reading and writing to registers on the device. These registers should co...

Hi @madmisha, You would want one. Damage is cumulative and at some point, the LED will probably stop working before it's time. thanks.

@abuhafss See: Page 508 shows the comm methods. Modbus via RS-232 & 485 or the Can protocol. NOTE: The 232 and 485 are not TTL (digital) sig...

@abuhafss What kind of servo controller is it? Some are similar to stepper chopper drives and have a step and direction, so GPIO and PWM. Others hav...

Hi @billd01, I assume you are using the string class. See the substring method in the string class. Also, you may want to look at pullup resistor...
