Hi Alastair, I would like to download Arduino code, wiring diagram, parts list and other resources. Where can I find these files please? thanks in advance!
Thanks for the video, it was very informative. I’m using a DFPlayer and a pam8403 amp for a project which I initially had noise problems with because of the wiring between them. I found that getting them as close as possible solved the problem. Also I’m powering them both from the Arduino which doesn’t seem to be a problem. I am using screened wires for that though. Thanks again. Your coding style is a lot more disciplined than mine. I’ve taken note! 👍🏾🤓
I love this and have had some success. The only problem I've had is that when I've put the smoothing capacitor in, my analog value starts at 0 and very very slowly rises up to 1024. I just omitted it before but now I'm getting a noisy signal that sometimes triggers when just one pipe is being held.
Same thing happened to me, took forever for the value to creep back over 500. I took out the capacitor (was using 100uf, he never gives a value for his capacitor) and that fixed it, I am not playing sound, just operating a magnet, so i just omitted the enum and switch/case left it as a simple if/else code and no capacitor, works perfectly. No interference. no false signlas.
Hey Alastair! I’m installing this puzzle but don’t know what to use for the metal bars. What metal did you use and how did you install it to make the handles?
doesn't even work on the breadboard. I tried the same circuit, the same programing. So first of all, there is something wrong with the serial. in the schematic you are using pins 8 and 9, in the programming you are using 2 and 3 (i changed the connections to 2 and 3). then If i plug in the computer to try to debug, doesn't map the device on any com. if I remove the power from the dfplayer, then there is no issue and I can debug. but the serials don't seem to work in the same time. second, I am getting really noisy signals even if I touch one of the contacts.I am using a 100uF. on top of that touching both contacts doesn't make any difference. still getting the same noisy signal back to A0 ranging from 400 to 1024.maybe I am using a wrong capacitor? I tried 220uF Doesn't seem to make any difference
Not working on me yet. I'm pretty sure, that it's not working, because the capacitor value is too big or too low. If i remove the capacitor, the value comes as it should be, but it's a little shaky.
