A small nit, so common that it must have worked its way into the EE text books. If you sample exactly at Nyquist, you will get a straight line. Of course you are reading the signal at exactly the same...

Hey Robert, I’m so sorry you had ti find this out this way. One can only have one thing be their favorite.That said I always watch the new product posts and also enjoy them on my lunch break, and in...

I think AtP is in a dead tie with Robert’s “New Products” (don’t head back to Chernobyl just yet). That’s one of the first things I check for every Friday morning, and I’m disappointed if it’s not...

If you need DTR at 3.3V, you’ll still want to cut/jump the trace. DTR’s got a level-shifting circuit on it, and it’ll shift the to whatever VCC is set to on the jumper. (Had to boost it because the...

Great Video! Quick (hopefully) question. I’m trying to sample a DC motor voltage, and it’s really noisy (brush noise, etc.). Is there a good way to do this with a standard arduino ADC (maybe an RC...

How would I hook this up to an arduino board to run a light board. Is it just like connecting regular leds in series and then connecting the positive to a pin and the negative to a ground?

Is this container decently water proof, ignoring the access holes of course? And is there access to the pins on the arduino? Seems it wouldn’t be very useful if there wasn’t but i can’t tell form the...

You cannot drive it directly from an Arduino, but you can add a transistor to the circuit. The Arduino activates the transistor, the transistor activates the relay. See the Relay Tutorial to see...

The Atmega ADC on the Arduino should suffice, and since DC motors are very noisy, always a good idea to do a LPF of any sort. The standalone ADC chips are very nice if you need to use more than a...

Yes, filters are the way to get rid of the noise. Consider the frequency range you’re interested in measuring, and make sure the filter you design falls well above that frequency range.You can use RC...

Nope – these take much, much more current, which the Arduino cannot handle. You’ll want to google for some Arduino projects that use these high power LEDs, they’ll generally use a constant current...

Does the CMD escape (“$$$”) appear in your data? It could be throwing the Mate into command mode. Waiting a minute gets you past the period during which the escape sequence will be recognized.

My computer is not showing this board in “Device Manager” (Windows XP and 7). Is it because it doesn’t have the bootloader ? or do I need to install any drivers for it ?

I have used this thread to make some fabric bend sensors and it works fine for what I am using it for, but I have found that it becomes less conductive over time. Is this because of oxidation of the...

If its not showing up at all it might be a bad USB connector. Contrary to the internet is rarely a problem with the bootloader, and you do need to be able to see the board before you can install the...
