@@davyS4v You wouldn't believe the amount of rabbit holes I went down trying to figure this out. This video was the first thing I saw when I was learning about this, and the wiring diagram was what I ultimately used all day trying to figure it out. JUST TO BE 100% CLEAR, tx gets wired to rx, and rx gets wired to tx!
Thank you so much! It is comments like this that motivates me to continue with the channel which some good news is I am coming back with bunch of tutorials and diy videos. Happy new year
Awesome tutorial! Detailed and very clear explanation. I want to kindly ask you for advice. If I want to use an OTG cable to communicate between the smartphone and the raspberry, how can I do it?
it should be possible I know someone connected the pico to a smartphone to use the pico as an oscilloscope really awesome stuff, this might be a great starting point www.tomshardware.com/news/raspberry-pi-pico-oscilloscope
Thank you. It will come in near future(ish), I am trying to make whole series on MicroPython then CircuitPython and then move to C for content not geared to beginners.
Very nice video! I guess if I want to be serious about this and make the Android app in AndroidStudio it will take days to do it, which is sad because I don't have enough time for it
I have not looked into the AndriodStudio just wanted to keep it simple as possible, but I know Processing is an alternative to make GUI applications that can be ported to Android.
Hey NerdCave, I am currently working on a concept to make a controller from a Raspberry Pi Pico I currently have it working via USB but wanted to incorporate bluetooth technology to allow connection wirelessly to the PC for controller functionality. Would the HC-05 work well for this, obviously ill need to write my own code and that should not be an issue. Everything I read about the HC-05 makes it sounds like it can communicate via UART and SPP. So this shouldn't be an impossible feat correct?
Yes, this should be doable since the bluetooth will be connected to the COM port on your computer allowing it to receive data, I am not sure about the python script you will need to write to process this data into controller commands, will probably be using an HID library in python to allow this. How is it working through usb now did you use the arcade hid library through the Pico
Well from the MIT app I would probably make a function and button to control the counter like up and down and send it. This might help to start out with: ua-cam.com/video/t6BioDDKJXQ/v-deo.html
it doesnt work for me. i dont know what the problem is. i think its an upload problem for uploading the code could you help please? edit: it works now i had to export my app to an apk and manualy give it acces to bleutooth awesome video
Hi, when playing with the HC-05 today I saw there is a tiny mistake on the schematic, the TX and RX pins needs to be swopped. I hope it helps
on your schematic or on hc-05?

Well constructed video with lots of information, thank you.
You are so talented with this, so clear so informative iam just impressed how you made it so understandable, bug fan here

Thank you for explaining the code, it makes it easy to understand
Glad it helped
Thanks, just what I needed!
Great to hear!

@@NerdCaveYT thank you so much. Alternatively are there other connection options than Bluetooth, Wi-Fi or OTG cable? 😂
Great tutorial - especially on the App Maker
Thank you, the MIT App inventor probably the easiest way to make an app
What if i don't want the led to turn on if 'led_on' is in it but only if it is that? (I dont want it to turn on if the message is 'turn the led_on')
I am not exactly sure what you want to do can you send me a message on discord
this is a good channel, good work, if possible make some tutorials for the raspberry pico with c language

i'm trying since 3 weeks but it doesnt work :(
do you have miss some steps?
All the steps are shown in this video along with the other bluetooth remote control car. What problems are you having?
@@NerdCaveYT led doesn't switch on/off but hc05 is connected. I follow every steps but it doesnt work
Did you find any solution@@davyS4v
Doesn't the Pi Pico have on-board bluetooth now? so we no longer need the HC-05?
The Pico W has on board-bluetooth, this video was made with the non Wi-Fi Bluetooth chip module
How to change a variable into the rpi script from app?

Great, thank you. I also struggled a bit since my phone does not have google playstore making testing really difficult.
