Re: How to build a working IR Artillery Gun
Posted: Mon Aug 14, 2017 10:50 pm
I have tried your coding myself. from your video - I have been investigating and it seemed to me for the Anti-tank gun project sd storage should be the option and amplification as I like it 'Lemmy" loud
I decided to give it another go and started again- hence the question on the forum
Success for me and having no feedback buzzing etc has resulted from using an an Adafruit 'menucomands" for the Adafruit fx board which has the gun sound embedded, I am not using the sd board (I have one but its not on this circuit) - Iusing other libraries has resulted in feedback buzzing etc with 'menucommands' it stopped
Maybe I need to do a wiring diagram for you to have look at?
One of my friends is a serious programmer and he is/going to look at this as well, hopefully he will have had a look when I see him on friday - we will see...
I need to look at this a bit further myself - note I am new to programming - i like problem solving and as its a challenge......

FYI
The only command that works is pressing P in the serial monitor on an R3 board.....
Also note the wav sound file has have 11 characters including .wav
The audio has to be encoded at 16bit otherwise it plays in slow motion - filename 'T00NEXT1.wav' is the one used in this video
Anyhow hopefully this is a building block
I decided to give it another go and started again- hence the question on the forum
