@zander There are only about 3 readily available pins, 22 and 27 are on a 4 pin JST socket with 3.3v and ground, and the only other totally usable pin...

@zander The "Cheap Yellow Display" has very few available pins, which is why I need the PCA9685. Here's some information about it:

Those are default settings, so don't need to be defined anywhere in a sketch, although maybe they are somewhere in a library where it would be a bad i...

Waking up this ancient discussion! I'm trying to connect a PCA9685 I2C board to an ESP32-2432S028 AKA a "Cheap Yellow Display", that has very few avai...

I think I'm going to give up on this. I was hoping it would be a quick and easy solution, even though it's not ideal, but it's getting to be too much ...

I don't use Wi-Fi, and my neighbours are some distance away as we all have big plots. The neighbours are all pretty computer illiterate, and I doubt i...

Thanks. It's not just whether it responds to Sixaxis, which the one I bought did. It needs to be tested with an ESP32 as well. I couldn't detect a Blu...

I'm in the UK too, which could be a problem, as what's available here may not be exactly the same as Bill can buy.

I got the PS3Demo sketch running on an ESP32, but it wouldn't connect to my controller. I tried the MAC address I got from Sixaxis Pair Tool, and all ...

A bit of progress! In the article Bill said "You’ll need to connect the PS3 controller to your Windows computer using a USB cable; one probably came w...

So does mine. I've also tried pairing it with a controller tester app on my phone, and my Raspberry Pi 400 doesn't find it. It flashes some red lights...

I'm in the process of trying to set up CCTV in my house using Pi Zeros for remote cameras, and a Pi 4 for the hub. I need a mixture of Wi-Fi and Ether...

It shouldn't be more than a few hundred milliamps, if you're using small motors like the ones Bill used, 130s, or N20 gear motors. I think the Wi-Fi i...

@troles, It's too easy to miss a bit when you copy and paste! Or add something by mistake! I'm currently carefully adapting the code to use a differ...

I've just tried doing this and it worked first time. Try it again, or download the files from the link in the blue Resources box near the bottom of th...
