Wow so much effort, just for 5V data pins. I usually stick to ESP32 if I need wifi... otherwise I like the respberry pi pico... faster chaper and 3.3V 🥰
@@playduino I've never tried it. But according to some documentation the Pico can achieve up to 1000kB/s on i2c. How much bus load is this matrix sensor generating? I really like your project idea. I'd like to build something similar.
I saw forum posts of people claiming that pico has a hard time driving i2c at 400kHz. You should aim for 1MHz to get the best frame rate. So I think esp32 should be the better option, but I have not tried it yet
@@autonoob Oh, I wasn't aware of such a nica and cheap ESP32 board, thank you. The RasperryPi Pico has some other nice features. The Pico1 accepts input voltage between 1.8V and 5.5V. This comes handy, if you want to "fire" it directly from a battery. And you have tons of pins available.
Your screenplay is again perfect. A very funny and informative episode again. Thank you.
Great video!
Great job - nice video !!
It's called a two wire interface because it needs at least three wires. 🤣
Can you share a link to the sensor?

Why use of arduino r4 when you have a nano or pro mini
Memory limit
can you use a external 3.3V fpowe supply?
yes, this would also work.

I agree, both esp32 and raspberry pi pico are super affordable, I think esp32 is a perfect fit in this case, looks like i2c of pi pico is also slower

But the esp32 supermini is only 2 USD. I just get annoyed now when things don’t have wifi or ble. Changing params on a webpage is just crazy useful 😉

I need your help
let me guess ... martens?
