Topic: Little help please... MP3/PIR (Read 411 times) previous topic - next topic



I'm not sure what the deal is here with requesting paid assistance but as per my thread over here:

Unfortunately, I do not have the luxury of time to keep throwing up errors and getting nowhere.

So before I painfully try to outsource this to someone in the Philippines I would like to offer the work here.
This is probably a 10 minute job for some of the guys on here but I will happily send £50 GBP by PayPal to whoever can come up with the required sketch and a short explanation.

Please drop me a message if you are interested.

The circuit is built like this:

With the addition of one of these PIR sensors (data pin connected to PIN2 on the Arduino) - https://www.mpja.com/download/31227sc.pdf
The data for the MP3 player is here - http://www.picaxe.com/docs/spe033.pdf
Must be based on the "DFRobotDFPlayerMini.h" library so that I can amend the code as required in future.
i.e. change volume with the standard code in the  Void Setup ()

•   The goal of the sketch is to trigger the audio by the PIR.
•   Randomly select and play a whole MP3 from the  SD card - In the case of only 1 MP3 being on the card, it will play that one each time.
•   Then stop playing when the MP3 finishes until pin 2 receives data from the PIR again (with a 5 second delay) - and repeat.
•   Essentially like a haunted house sketch.

Please message me if you are interested in the project. I need the sketch pronto!



In case you don't get any responses, here are some possibilities why not:

1) Nothing takes 10 minutes. I could spend the next half an hour just reading all the stuff you sent and understanding what you need.

2) To test properly, the responder needs the hardware. If you won't use what I have on hand and I have to order hardware you need, I'll typically do it at a 50% markup since I have to cover my time searching for parts and the actual time of ordering. Remember there's also time to wire everything up and verify it's working with whatever sample code they supply.

3) Actual development after all specifics are absorbed is probably under half an hour, but not ten minutes.

4) Add time for testing possible error scenarios if you want a professional job done.

5) Nothing takes 10 minutes!
Electronics and firmware/software design and assistance. No project too small


Thanks for the feedback. In retrospect I appreciate 10 mins was a flippant comment.

I have subsequently realised that even just providing the scope is a fairly time consuming task. I am therefore still trying to complete this myself for now... Fingers crossed



In just 13 minutes? That's fast! You apparently weren't that far off with your 10-minute estimate (of course you did have a head start knowing the project in and out :-))
Quality of answers is related to the quality of questions. Good questions will get good answers. Useless answers are a sign of a poor question.
