May 15, 2012 - i second jblates' comment, you have a definite way of breaking down the complex :)

May 4, 2012 - Nice video man

May 2, 2012 - Great vid thanks but how would I now use this with a bi-coloured led (two prong) to change colour when the button is pressed

jblates Says:

Apr 29, 2012 - you my friend, are going somewhere.

Apr 29, 2012 - Thanks for the great tutorial... I like your presentation style and format. Very easy to understand.

Apr 27, 2012 - The reason this isn't good practice is that it is easy to imagine boolean being implemented as a true bit value, able to be only 0 or 1. It is equally easy to imagine LOW being defined as 0 and HIGH being defined as, say, 1000 (they are, after all, just arbitrarily-defined manifest constants). Then the value of HIGH wouldn't even *fit* into a boolean ...

pseudorandomly Says:

Apr 27, 2012 - This is a good observation, and what you see in the video is not what I would term good programming practice (I've been a C programmer for 35 years; I started not long after C was invented). In C, "false" is 0 and "true" is anything other than 0. I haven't actually looked at the Arduino code, but I'll bet that LOW is 0 and HIGH is, say, 1. So LOW is false and HIGH is true. But you're correct that the code would be in trouble if the definitions weren't compatible in that way.

Apr 26, 2012 - lol, I find it pretty weird to see a variable of type boolean with a value of either 'LOW' or 'HIGH' instead of 'true' or 'false' ... is this normal? (atleast not in Java) If so, can somebody explain? I'd like to figure this out and understand this. Thanks in advance!

Apr 25, 2012 - wow this is rocket science

Mau1wurf1977 Says:

Apr 21, 2012 - My bad they are indeed PWM :)

Mau1wurf1977 Says:

Apr 21, 2012 - Are you sure that was PWM? Because AFAIK analogWrite just sets a voltage between 0 to 5V?

tboltz7 Says:

Apr 21, 2012 - nice tutorial, can you help me with a project i have. i am trying to use an arduino for a boost converter for photovoltaic system

Mau1wurf1977 Says:

Apr 18, 2012 - Excellent tutorials! What camera are you using?

Walternzani Says:

Apr 14, 2012 - @sciguy14 I dont know if you are getting a raspberry pi, but if you are, would you please do a tutorial series like this one. It would be really helpful. Thanks.

Apr 14, 2012 - i found it out but thanks for the reply and the help!

Apr 9, 2012 - I like your examples in the C functions and code. However, I was hoping your tutorial would show how to use the arduino built-in PWM functions so I dont have to go out and buy a Pulse Width Modulator (PWM) Unit.

daniel244king Says:

Apr 9, 2012 - This tutorial is a GREAT example for beginners. This is a tutorial for the arduino microcontroller, NOT C or C++ (which the arduino code is based on). If you want to lean C then google: C tutorial

daniel244king Says:

Apr 9, 2012 - I think this is great. For you beginners who think this is too fast; I have five words for you: google, firefox, addons, downthemall, videodownloadhelper.

Apr 7, 2012 - For those of you guys who don't understand this tutorial check out Java programming or C++ tutorial by bucky, for a basic understand of programming(variables, loop and stuffs), or go to arduino official website there are few tutorials there explaining about variables etc.

flyingchimp99 Says:

Apr 7, 2012 - This is all going to fast for a beginner. I dont really understand much of what your saying

lonelywolfie0 Says:

Apr 5, 2012 - no offense but i agreed this is too much for beginners, i can't understand its too much information at once. just some suggestion try to slow your speed down...
