That's quite impressive, not an easy thing to achieve that accuracy.

I like how you stamp it rather than try to drag the pen, is this how you get better accuracy??

First time posting! I was looking at the IR python repo posted above. I am curious how the 38khz carrier is being accomplished on the esp32? I just made it work after hours of poking and my solution was differents. What I did was find the esp32_rmt.c file and change the values for tx config, and bi...

It is not so much STM fan boys but more correct information. I use both ESP32 and STM32, started with ESP32 barbecue of price but ended up mainly using STM32 because of the random ghosts in the machine with ESP32 and also was always running out of pins on ESP32 for my robot projects. There has been ...

What is the equivalent on the PYBD? How about connecting a camera to the PYBD? I have not looked into this, but I don't think it's nearly as easy as with an esp32 and even if the HW supports it I didn't find code out there when I searched (maybe I overlooked the obvious). most STM32F4 and up have a...

I am not sure if you will find code for microbit but from the links above you can understand how it works and write your own code

I have used this bit if hardware https://www.ebay.com/itm/1Pc-Portable-Infrared-IR-Wireless-Remote-Control-Module-Kits-for-Arduino-T-Jh/124160732819?epid=0&hash=item1ce88e6e93:g:71cAAOSwT2daRZgF just recently for something similar but it was for my 6yrs robot which is a Mbot (ardunio MCU programmed ...

@Mattyt usually thoroughly tests his libraries before making them pubic and his demo code is very simple to use so I assume either your APA102 are damaged and not working correctly or your connections are incorrect.

1 timer can control 4 servos as they will all be on the same freq just different duty width. You shouldn't really need a timer callback to time the freq of moving the robot as you should just be able to take the time when entering your loop then next time around you wait till the time is what you ne...

The LEDs will need 5v supply to run.

You ESP32 board should havea 5v supply from the USB input.

Is this your board??

If your only going to be running 10 LEDs you can probably run them from the ESP32 5v pin but wouldn't run larger amounts (Ardunio power supply isn't any better than ESP32).

Do you also have a common ground to both the power supply and the ESP32???
