    hey jeremy i was thinking instead of adopting the use of a voltage divider why not measure the increase current through the resistor, use? a shunt resistor and send the voltage across the shunt to the arduino. Will this allow a greater resolution?

    @WebDesigneri If it only have two pins, how is it being varied? You can set it up in a voltage divder circuit with a fixed value resistor, and use the output voltage to determine the value of your variable? resistor.

    Hi! I have a …
    Hi! I have a variable resistor that can be set from 3.34 to 8.72 kohms. What’s the best way to read the position of the variable resistor with an arduino and get the best resolution? The variable resistor has only 2 pins, so it doesn’t work like a potentiometer.?

    I’m wondering if anyone on here could take a look at a few lines of code that I have written. I am trying to just make sure a small video camera stay on and stay recording, I am going to put it in a weather balloon. I believe it to be very simple code (to someone who know what theyre doing) but I have had some trouble with the REC button working. I have sent Jeremy Blum a msg? directly via FB but he? never responded. Please respond to this post if ur interested or email bryan246@gmail.com thanx

    Hey, question- i have infrared sensor and everything but the the JST connector which connects the sensor to the breadboard is actually aluminium( that reddish-? brownish fiber like thing) and not copper. Will that make any difference? Help

    Hey great video. 🙂
    Well, i did order the arduino starter kit so thats not a problem. But, i did order the infrared sensor(short range) but that did not come the connector( the jst connector or whatever it is called) 🙁 How should i connect the sensor now? Is that cable available on element 14 website? Or is it? available everywhere?

    Can you actually use the 3.3v pin on the Uno board to power a sensor that requires 3.3v? and at the same time use that as the Vref?

    @sciguy14 Yeah, for some reason when I see programmers put brackets underneath voids, booleans, ints etc. it always bugs the crap out of? me for some reason
