I really enjoy your channel. I have learned a great deal from it and the ability to ask questions is a bonus. I have a question regarding the use of a DC motor with an attached quadrature encoder. I am using a model JGY-371 12V DC motor with the ESP32 for my project. I have tried the encoder library and the ESP32 encoder library, and I cant get them to work. The ESP332 encoder sample will not compile on my ESP32. It returns a code that the "attachFullQuad is not defined. I would like to be able to spin clockwise and counterclockwise freely but also be able to move a certain distance and return to the same spot. I am not using this to drive a robot or anything that moves forward and back but rather up and down. Any help or direction from your viewers would be appreciated.
Have you looked at my ESP32 Rotary Encoder video with example code for Arduino ruclips.net/video/74KCgCAoawA/видео.html. The example can, with minimal changes, with a standalone rotary encoder.
Hello, have you planned to show us more content from the ESP32 series under Eclipse or you are planning more in the Arduino IDE? May be how to solve some SW or HW design issues. For example low power applications or BLUETOOTH / WIFI MESH ..... whatever you have in your mind. I like this channel technical parts, thank you for your contribution for us!
Arduino esp32 .How to generate single sine wave impulse with pwm using array like "int spwm[ ] = {1,5,15,40,75,115,180,230,254,254,230,180,115,75,40,15,5,1". And repeat it with 50Hz frequency. Ledpwm not been able to change duty corectly in every consecutive period at all. Any thoughts how it can be done, may be by using rmt. Thanks.
Anything??? OK, here i go ... I have a issue since a certain time : How to get a 4004 LCD (3.3volts) on 1x I2C backpack, so it can be used with just 2 wire interface on the ESP32.... I tried with 2x backpacks, tried with 1 backpack, tried 5.0v 4004 LCD, tried 3.3v 4004 LCD (broke all two of them :-( ) I have multiple DC-DC stepdown buck if needed.... Maybe, just maybe, you can help me out :-) Thanks in advance, Yves
Could you do a vídeo using esp32 with Arduino IDE as a BLE UART server that periodically connect to Wi-Fi and send data to a cloud? I’ve seen so many people having problems with it, including me
Here is a slap together example github.com/pcbreflux/espressif/tree/master/esp32/arduino/sketchbook/ESP32_BLE_server_UART_Thinkspeak sure you have to change ssid, pass and WEB_URL to add the Write API Key from thingspeak to fit your need. And a little more testing is needed, but all in all it should work stable. The Arduino BLE library from Neil Kolban uses bluedroid and this seams to prevent HTTPS from working, to get arround this and also to prevent the BLE server to stop, the sketch uses deepsleep to start the esp32 from time to time. The Values are stored in NVS (non volatile storage) and are send to thingspeak after a startup.
Thanks for giving us the opportunity to ask you anything, here is my question: What is your day job about?
Hi, nice idea. Love the technical details your vids, keep it up. What is your profession and field of work?

you always use the ble400 board with stlink jtac. is it possible to use the usb port on the ble400 to program the nrf51822 from linux?

Can we you show how I can use tasmota firmware on node mcu? I find trounle in using it ...on node mcu
could not get hold of the nRF52840 dongle in Germany. any recommendations where to get it?

Hi, could you make an episode how to use a ky-040 rotary encoder with the esp 32 without blocking other running code and minimal hardware?

thank you. I will try it and give You a Feedback
