I am using a stand alone ATMega328P in the final circuit and here is the ATMega328P pin out compared to the bread boarded circuit:

enterprise 11
enterprise 111280×1024 243 KB

I have a 12VDC/1Amp and 5VDC/4 Amp wall power supply.

When I power it all up, I have 5VDC at pins 7, 20, and 21. According to the sketch, I should have the LED's attached to pins 7 and 8 on. The LED attached to pin 5 should be on and sound should be heard out of the speaker via pin 15. Instead, nothing is on except the LED on pin 5 and either the LED on pin 23 or 24 is blinking, no sound but static instead and LED's attached to pins 7 and 8 are not on.

I am a beginner writing code and the Arduino board, but I do have a degree in electronics and worked on electronics in the Army.
What could be my problem?

Welcome to the forum

You appear to be using the chip pin numbers in your sketch rather than the Arduino pin numbers. Is that deliberate ?

3

These look like physical PIN numbers... that is the pins on the actual chip 1-28.

In your code you should be using the logical GPIO Pin numbers.

This pinout diagram might make it clearer... in your code you should be using the Brown numbers in your code.

For example PIN 5 is physical pin 11 on the chip.

Yes. I used the Arduino board to build and test the circuits first.
So when I changed everything to the stand alone ATMega328, aren't I supposed to change the pins to correspond to the chip.
Here is the bread boarded circuit:

No

Use the same pin numbers as you used with the Arduino board. The compilation process will take care of the mapping

WELL DARN IT!!!!!! That makes a lot of sense! I learned something new today.

The person who originally wrote this sketch had it that way. I assumed you had to change the pins numbers to correspond to the actual chip.

Thank you, I'm going to try that in the morning.

where can I find this picture and a explanation of what each color and/or column means?

Thank you goes out to @red_car and @UKHeliBob for pointing out my mistake with the pin number call out in the sketch. It got a majority of all my lights working.

Now I am having issues with the sound and the lights attached to the shift register and Darlington driver. This includes the "RED ALERT" switch and LED. I am not getting any sound and no LED's lit up that are attached to the ULN2803A Darlington Transistor pins 12 to 18. Below is the bread boarded circuit for the speaker and Mini SD reader.

Is there something wrong in the sketch?

You appear to have a MOSFET connected to pin 9... but nothing in your code refers to pin 9 ?

Where is the LED connected?

12

And here is the circuit for the "RED ALERT" led. It's in the center of the smaller bread board. It's the loan red led and push button:

Yep sorry missed that.

There's a lot going on in that circuit... did you try testing with just a few components?

14

Yes I did. It a YouTube tutorial and the original author of the sketch breaks up the sketch and circuit into several different videos. For example, the first video was on the "strobeLights" and navLights":

So when it came to the sound effects, it was a separate video with just the "audio" circuit. Then he adds the "audio" sketch to the "complete" sketch and the circuitry to the complete circuitry.

If you want to get a better understanding of what I am doing, here is the guys YouTube sight:

15

And how does that button work. Connections seem strange to me...

16

Is your power supply sufficient to deliver power to that speaker?
Is it 8 ohm?
It will be quite noisy...

What happens if you connect any of the uln inputs to 5V or ground? Does that light the LED? That woukd prove the uln is ok.

Can you measure the voltage of these inputs during normal operation? That would show if everything before usb is ok.

Hi,
Can you please post some images of your project so we can see your component layout.

Can you please post a schematic, not a Fritzy.
Reverse engineer your project and DRAW a circuit diagram and post an image of it.
Please include your power supply and component names and pin labels.

Thanks.. Tom.. :smiley: :+1: :coffee: :australia:

Did you do that bit of the project in stages like he did, so each stage works, BEFORE connecting everything up.
OR did you just connect everything up as in the last segment of the videos and just load the final code.

If so can I suggest you go back to the tutorial and do all the steps to make sure your hardware connected and can be software controlled.

Tom.... :smiley: :+1: :coffee: :australia:

I built this circuit and NEVER got the red alert to run properly. I had to rewrite the whole sequence. And I don't code, so it was a lot of trial and error. I also changed to a DFPlayer, then finally to an Adafruit sound card, as the sound quality from the SD Card adapter was very poor.

And then my model flew off the shelf (the power units done broke) so I am building another, but I am intending to re-do the circuit. (I even designed a few PCBs to help organize the thing. But I always missed something). My major problem was using negative ground- and with NPN transistors and MOSFETS, the circuit called for positive common. So, eventually, it only half worked before the ship was destroyed. Doing it properly, now.

How are you doing with yours?

The two circuit boards on the left are independent from the ATMega328, Darlington transistor and shift register. Each one runs a separate 6 LED chaser circuit off of the 12VDC power supply. It works fine.

The bottom left board holds the ATMega328P chip and the upper left board mounts the Darlington transistor and shift register.
