    Potentiometer characteristics

    How so, in the above referenced design, you wired a string of LED's on a two sided pcb, with legs on each side, that is a parallel circuit is it not? He didn't say that he was using a 3 or a 5mm LED, did he? Here is a link for some high current LED's from Digikey.

    Good job! Alas, I won't be of much further use. Perhaps a more experienced member will be along soon ;-)

    A likely place to investigate, just be careful of those ribbon cables, they are very delicate! I have had limited success with pulling them out. Sometimes you need a good pair of pliers, but pad the jaws with some duct tape.

    Suggestions for building a PIC dev. board?

    Yes, I think its rather clever. To be clearer, other dev. boards have different modes of output whereas the PIClick's outputs are all tied to a transistor. That is what I was commenting about. Take for example, this board...

    Potentiometer characteristics

    Colin, do you love to argue? Where you one of those children that just had to be right all the time? LOL :D Let me spell this out for you: Visually with our own eyes, I don't think we can see the difference that 3mA will make at the top of the range of the LED. On the other hand electrical...

    Potentiometer characteristics

    I am sorry you can't understand my "Emglish" :D - what part did you not understand? Can you tell the difference in how bright an LED is when there is only a difference of 3 mA while at the top of its range? I doubt it and thus explained it so. I recall seeing a video of you and you are a native...

    Suggestions for building a PIC dev. board?

    I understand that each pin can only handle 25mA max current, I was conveying that the design was very basic in that all you see is each port with a transistor on it whereas other boards have various i/o assigned to different legs. The picklick seems to have been built solely for output.

    Suggestions for building a PIC dev. board?

    Thank you Colin for finding that! The pick lick is a very basic design, relying on a transistor to sink a current for each output. I liked the PIC Lab better - more variety of "peripherals".

    @scrumpet So??? How did it go?!

    Suggestions for building a PIC dev. board?

    I appreciate the response Colin, and I have been to that page and several links from it, but was unable to find a developer board. Thanks anyway, Happy New Year!!

    Potentiometer characteristics

    Welcome to the forum Nassim, you may want to read this resource before proceeding on LED's. Assuming that you have your 5 led's in parallel and they EACH have a resistor, each LED would receive about 27mA of power. Are you certain your LED's can sustain 30mA? Three more mA and you are at your...

    Hi Goat, have you tried their website, they have a forum: http://live.altium.com/#signin

    Simple project needed

    That is certainly small enough :-) impos1 - will your control circuitry shut the motor after a certain time or upon button depressing like an alarm clock?

    Suggestions for building a PIC dev. board?

    Thanks Colin, do you have a link to your dev. board? I looked at the website, but find it hard to navigate. I don't think the pic below is what you are referring to and the other link had no photo's of the board. Thanks from: http://www.talkingelectronics.com/Articles/images/Prototype-2.jpg

    Help Getting Started with PIC Microcontrollers

    Funny you should mention that, I did come across that today when I was looking for dev. boards, thank you though, I already saved the intro page and will look it over lunch today :-) Thanks again.

    Do you have a google account? If you do, you can upload it to your G-drive and make it a public link and send us an invite link or post the invite link here. I am sure other similar services would work.

    Suggestions for building a PIC dev. board?

    I am interested in building a development board for PIC μcu's. I know that this is a broad area since it depends greatly on what PIC you are using and what i/o you want to use/have read in etc. This is where I am having the difficulty. I don't know what I don't know! What should I as a novice...

    Sorry mate, but we will need tighter pics with better lighting to see any defects.

    I would certainly start at the psu! Just because it powers up doesn't mean the power is stable enough. Yes, pics are good ;)
