1:03am 02-06-2013 tejh: I'm used to putting 2.2k ohm resisters in series with an LED for 5vdc power. this says 56 ohm. Seems like a huge power flow. lol; Replied on: 1:33am 07-14-2013
Yes, LEDs will still light with very little current.

8:32pm 01-16-2013 JOSE: I am looking a kit of stair lights, could you tell me if yours works with 12 volt LED lights. If it is not possible, could you make one of 12 volt and how much is for it. Thank you. Jose Gutierrez

11:14pm 12-16-2012 EDGAR: Hi, i am trying to design a temperature controlled fan using LM35DZ. i have tried a number of circuits using lm741 opamp and lm358 dual opamp but nothing seems to work. i need your help in terms of a circuit diagram for this circuit. please

7:02pm 12-15-2012 Faraaz: Hey Alan,

I am a beginner electronics student at Millikin University and chose your PWM fan controller as my final project. I looked at your schematic and I don't know where collector of the NPN transistor goes. does that go to one of the leads on the molex connector of the fan. Any help would really be appreaciated.

Thanks

That gets connected to the negative of your fan. This is probably the black wire in your molex connector.

9:32am 12-06-2012 Carol: Alan,

I saw the project of the Hard Drive Clock recently, so I decided to make one for my final work at technical school. Could you tell me some hints to make this job easier? I thought of using three colors of LEDs instead of two, for a better view of the colors, mainly under natural light. In what language did you write the source code? Could you send it to me?

Waiting for your response,

Carol.; Replied on: 9:47pm 12-15-2012
You can get the code here.

It was written in PicBasic Pro

5:38am 11-24-2012 Lukasz Wr: Hi. I'm student on electronic.. I'm starting my adventure with microcontrollers.
This project is great! I built that.. I'm searching source code (program lighting leds step by step). Do You have that? Could You send me? or could I buy it from You?
Please help

9:27pm 08-25-2012 marco Avendaño: hi Allan mi name is Marco Avendaño from Bolivian please I need project propeller clock Build but pic please send me cost send la paz in Bolivian in kits ensambled tanks; Replied on: 12:37pm 09-27-2012
Hi Marco,

Everything that is available is shown on the project page. There is no kit for this project.

2:17pm 07-04-2012 Lucian: Hello,
I built the Stair Light project and everything works great. Thank you so much. I have a small request to make. Is it possible to send me (or buy) the source code for step by step lighting. I have the "all led on" version but I realy want the version to light each led step by step. Thank you so much, Lucian; Replied on: 12:41pm 09-27-2012
Yes, the code on the site if the basic one. Please email me for the one you would like.

8:59am 07-01-2012 David: Hi Alan!

Thank you for stair light project. It works perfectly. Is it possible to get the hex file, version 1.3 or 1.4? I tried to MicroCode Studio (MCSX) but show me an error. I have no experience with this. It would be very happy if they could get the new version.
Best regards
David

P. S. Sorry for my english.; Replied on: 12:44pm 09-27-2012
Please use the 2.56A version of PICBasic Pro.
