Since my first post, I have reduced the POT to 50K and I've used the code example given in the PBP book to adjust the scale and my value is now set to 30 so this is a mystery but I am not so...

I actually have a blue LED 3.5V forward, I just tried with a red LED 1.9V forward. The whe I hit 3.9V the PWM doesn't work, the LEDs remain at full intensity (Dimmed by the lower voltage but no...

As the circuit will not work under 4V I guess I would need to supply 5V so I will be using a 6V SLA battery. I think I will stick with a couple diodes. About reducing duty cycle I was under the...

I am presently powering the circuit from PICKIT2 but this circuit will eventually be powered by batteries.
The DC motor requires 1.5 to 4.5V and the datasheet for 628A indicates an operating voltage...

When drawing the schematic I had the LED reversed.

Setting the duty cycle to 0 instead of stopping the timer gave the following result:
Dim for 1 sec
Full on for 14 sec
loop

So I reversed...

Thanks for your replies.
I will need to do some extensive reading on the first option as it might be more efficient but I tried option 2 (the long way) and it works.

Now I have something that is...

This is probably an easy one but I have been off this stuff for a while and I am a little lost. I read the book and searched the forum but I can't find the answer.

I saw this link, I will use this as a starting point and I will try to convert to PBP.

Thanks

Hi David,

Did you ever get around to do some development on the DHT11/22 ?
I've just purchased a bunch of both from eBay and I was hoping to study while I wait for my order.

Thanks Dave for the suggestion but that is a little too much hardware changes.
My project consists in a stream of LEDs lined up in a tube and I am trying to keep the hardware to the minimum.

I am still struggling with this, however I am a few steps further (I hope):ambivalence:

and slightly modified it to scan one way but I have 2...

I would have liked to delete thread #18 because that issue was resolved, I was missing some piece of code for MIBAM.
Anyways, I started off using Sayzer's code, then I was able to bypass the POT and...

(Post removed at user's request in next post)

I will give this a try.
which PIC are you using? I can't read the text in the picture.

You are using one resistor per column, is it right to say that no matter what, there is only one LED ON at a...

I played with the settings and the LED is now dimming.
I am now facing my first issue... how to produce the effect I want.

I will try to find more examples, there's lots of scrolling text but so...

I'm trying...

One MIBAM output (B0) going to a resistor then a LED which is then connected to VDD
Using a PIC16F628A with this code the LED remains on with no dimming.

I think I am starting to understand BAM and I am not sure this applies to what I need to do.
Fist I should specify, I indicated in the subject "flying star" as the french that I am but "Shooting...

I was looking at MIBAM but then moved away due to its limitations:

I am planing to use 64 LEDs (maybe more) and I am trying to keep the components to minimal.

I haven't figured out if the above...

Yes I realized that's what you meant after responding. I am presently in a test environment and just using a LED bar graph type and pushing +/-5mA
My final product will probably have transistors for...

This is going to be handy, I've been pulling my hair out all day trying to figure this out.

Thanks for the link.

Hi Henrik,

It does not show on my drawing but I have a resistor on each led's anode.

For the scanning part I think I see what you mean and I will play with my code. I presume I should make two...

The theory in my head was quite simple, I connected 16 LEDs in a matrix like so:
6195
but physically they are positioned in a single row from LED1 to LED16
I am testing with 16 LEDs but ideally I...

Thank you Darrel for the clarification.
I guess I will look into getting PBP3.
