It works with the Esp32 module DEVKITV1?. I tried but on the serial monitor of the transmitter the message "Error sending the data" appeared, on the serial monitor print received values it shows the message "No Signal". I did all the steps and put the MAC address but it didn't work, probably the problem is that my module is Esp32 DEVKITV1. I don't know, can you help me?

Same problem bro, i am also facing same issue. So please give me working code.

[@Sj-yf2jg]

I have found the solution, the main problem is that this video provided esp32 code is old. esp32 updated their esp_now protocol receiving code. Arduino IDE 2.3.2 uses the latest esp32 library, When you use this old code then IDE shows Error Compile.

Can i change switch with a joystick to control more Servo

[@hashincludeelectronics]

Yes you can 👍🏻👏🏻

[@elektron2kim666]

Motors (+) should have their own power. It solves the problem with higher currents, volts, watts as well. Power 1 = Micro Power 2 = ESC ----> Motor Micro signal/ground ESC A few "toy motors" probably won't hurt, but you will run into issues all of a sudden. You can also run brushless (3 wires ESC) in what I'm saying.

[@hashincludeelectronics]

Agree 👍🏻👏🏻

[@cipitillo]

question to get a ground signal on the led pins instead of 5 volts do I need to to change from PULLUP to PULLDOWN?

[@hashincludeelectronics]

As far as I know we use PULLUP and PULLDOWN for input pins. Not sure if you can use it for output LEDs . 👍🏻

[@cipitillo]

Because a need a negative pulse or ground to triger a mp3 board

[@cipitillo]

Do you think if I apply 5 volts to the switch I will get ground on the output receiver board

[@hashincludeelectronics]

@@cipitillo you can write LOW to output pins which is nothing but ground .

Hi Mate. From Australia, thanks for the great info. One question, how can I smooth the servo motors. The power supplies are regulated and I made sure the issue is not coming from the supplies. Servos keep shaking, even when not operating.

[@hashincludeelectronics]

Check the power supply at transmitter as well .

[@KalyanProdhan]

It is called servo jitter. Internally, if the settings of the pot is not proper, it happens. I would recommend you to replace the servo, and put a good one. We just replace the servos in aeromodelling. One in hundredth servo has this kind of manufacturing defect for cheap 9 gm servos.

[@amirmohammadbavarsad4718]

Thanks for the video, but I have a question how to do this project with nrf24l01 and esp32 for longer range?, all nrf24 codes are for arduino nano.

[@hashincludeelectronics]

Esp32 itself has WiFi onboard . You don’t need to use additional rf module .

[@orange_tweleve]

​@hashincludeelectronics he was talking about the range and esp32 is terrible at that. Also I don't understand, the esp32 is way too overkill for this project, why not use a shift in and shift out chip on an arduino nano to have a LOT of input/ output channels and the basic 8 channels for servo control ( or 6 channels if you wish to incorporate an oled )

What the range of control we can get, if we use ESP32 modules as transmitter and receiver (If we can use this for aeromodelling Transmitter and receiver) ?

[@hashincludeelectronics]

The connections to GND and the disconnected meandered antenna trace are just to brace the pin soldered to the main output trace and help to prevent if getting torn off. My actual antenna is just a single wire with a female dupont connected to the ANT. I haven't done extensive testing yet and I'm curious to see if it'll work as a dipole if I stick another wire on the ground pin or if I'll need some sort of balun.

video ok but my code not works some thing is missing

[@hashincludeelectronics]

What version of Arduino iDE are you using ?

[@belajardanberbagiapapunitu4246]

is it possible to replace both "ESP32" with "ESP8266", Thanks in advance

[@hashincludeelectronics]

I have not tried that . I would recommend to use only esp32 to not face any issue 👍🏻👏🏻

[@miniaturecreations772]

Hey hash , very nice vid ryt there brother, we can use esp WROOM 32 for making the receiver small isn't it?

[@hashincludeelectronics]

Thanks for checking out the video 👍🏻 I used the esp wroom 32 breakout board . Yes you can use any small board like surface mount devices .

[@miniaturecreations772]

Thanks for clearing the doubt bro, keep these kinda builds coming 💜

[@hashincludeelectronics]

@@miniaturecreations772 always . Cheers 👍🏻

sir pls make wireless water level indicator with 8 to 10 steps, pls use seven segment display and with esp8266 or esp32 pls use espnow protocol thank you sir

[@hashincludeelectronics]

Sure will try to do that 👍🏻. Do you want it to be controlled from anywhere in the world ? Or locally ?

[@sonu9999208499]

Sir, I want to do another programming of controlling 14 DC motor with L293D IC in esp 32 so how to do programing of transmitter and receiver. Can you give me a program of transmitter and receiver for controlling 14 dc Motors with L293D IC.😇😄

[@hashincludeelectronics]

Unfortunately I could not be able to provide it . It needs coding and testing as well. You can give it a try 👍🏻👏🏻

very nice!!

Which version of Arduino IDE are you using?

[@marscreation.s]

Please make a flight controller for drone with esp32

[@hashincludeelectronics]

You can use this transmitter receiver setup for drone control remotely 👍🏻👏🏻.

[@marscreation.s]

I want to control drone using mobile phone.

[@marscreation.s]

Make a drone reciver with flight controller for coreless motor drone which I can control wifi.

[@hashincludeelectronics]

@@marscreation.s oh ok . Got it . Sure I will try that . I have drone kit but did not get a chance to work on it further . Anyways I will try 👍🏻👏🏻

Hi i try to compile it come this error (Compilation error: invalid conversion from 'void (*)(const uint8_t*, const uint8_t*, int)' {aka 'void (*)(const unsigned char*, const unsigned char*, int)'} to 'esp_now_recv_cb_t' {aka 'void (*)(const esp_now_recv_info*, const unsigned char*, int)'} [-fpermissive]) CAN HELP ME PLEASE!!!!!

[@hashincludeelectronics]

Please install required libraries as shown in video . 👍🏻👏🏻

[@Makeshotff]

We can use esp8826 also

[@hashincludeelectronics]

Not sure if we can use that . I would recommend to use only esp32 module in this project to avoid any issue 👍🏻
