When we were kids, we used to make wooden guns to play with. Today, after 25 years, I have made such a gun again, of course, a bit more modern. I used an ESP32 and the Arduino IDE, along with some additional components. I will put the link to the entire YouTube video in the comments. 315.by aoab50. I made a very simple test on ESP32 and on STM32f411 (blackpill) using Arduino IDE to count the number of loops the microcontroller will go through in one second. The number of loops for ESP32 was 762,082 while the number of loops for the blackpill was 1,477,468. The ESP32 runs at a clock speed of 240MHZ while th blackpill runs at 100MHZ.ESP32 is a good choice for robot controls. It comes with wireless (WiFi, *Bluetooth Classic, Bluetooth Low Energy) communication out of the box. Also has enough peripherals to control motors, LED and everything else. Power consumption is a bit higher, but this doesn't matter if you use it to drive motors. The Matter SDK is an open-source repository for the implementation of the above-mentioned connectivity standard. ESP32 has been supported in the Matter SDK since the very beginning, and it is currently the only option which can offer both Wi-Fi and Bluetooth LE connectivity. Furthermore, ESP32 supports commissioning (for the initial …We had esp32 cams and we basically just removed the filter on the lens, it’s pretty easy to remove using a pointy knife. However, if you want to use for both night and day, you’ll need the filter on during the day and out during the night.

Plus, you'll be really slow to get to understanding esp32's native API and build process because you'd do it only when you face some very pesky problems. Doing any serious ESP32 work without understanding decently esp-idf is bad idea.There are no predefined pins for that on the S2 and S3, unlike the traditional ESP32. I believe this is because the S2 and S3 don't have the remuxing speed penalty that the regular ESP32 has when remapping SPI off the default pins. Here are the pins I used for the ST7789 display. If you use something like an ILI9341 that has a MISO pin, you'll ... Esp32 Esp32-S2 Esp32-S3 Esp32-C3 Esp8266 Raspberry pi Pico w So I would pick either the S2 or c3 if you need Bluetooth.
