ESP32 LED Control from Anywhere (IOT) With ESP Rainmaker and Arduino IDE

A viewer was having trouble making a dimmable LED that he could control from his phone using ESP Rainmaker on an ESP32. This video shows how to quickly code up a solution that works from anywhere with your phone.

Don't forget to leave a like 😀

Hoping to try or see the code for the servo motors (for smart curtains) and non addressable RGB lights (smart lights)…

Excellent very educational video. Could you please make another one with the thermostat function. With DS18B20 and also with DHT22 I thank you in advance

Thanks for the great educational video. May you please do a video on how to activate a relay in rainmaker for gate automation. Eg the relay must toggle for 3 seconds only like pressing a gate remote to open and close. At the moment all the you tube videos shows only how to turn relay on or off.

Hello
Thank you very much for sharing your nice and simple program
I managed to change variables such as temperature, humidity and timer time in the program by using your program template and slider definition.
Thank you again

Thank you, John Macrae very much appreciated Sir

Looks like I must have a look at this some time, its a nice use of passing data between phone by just reading and writing in to a struct and letting the callback do all the work. Reminds me of early esp8266 days, where all the programs were just a set of event driven callbacks.

Hi, excellent project.How can we retrieve the last state on power resume after power fail? Could you please advise?

[jonatanboy]

Something i have been trying to wrap my head around the last few days.
is the ability to have dropdowns in RM.
Was hoping to add a few FastLED effects in a RM install, so that i could use a Button or touch to switch modes and dimming.
I feel like it should be possible. But i Seem to find myself lost looking for examples of anyone having a similar idea 😂

[masoudjafarzadeh]

Hi dear friend
While admiring you
I have a question
I wrote a program in which I want to use the following command to send an important message to the phone
esp_err_t esp_rmaker_raise_alert(const char *alart_str)

Can you show me its format with an example?
Thank you again

[masoudjafarzadeh]

Hi
Why dosent work on off switch in here?
Thanks anyway🙏

[orielbaptista]

is it possibe to to add a color control wheel to a led strip?

[tinayoga]

It looks like you soldered the LED without a series current limiting resistor. Does that LED have a resistor included internally? Or are you relying on the limited current drive of the port pin. (not a good practice)

Hello Sir, I have been following you on youtube for some time now. You have posted a lot of great videos that I have gotten nice ideas and solutions to. Recently you posted a video on ESP RainMaker Cloud and how it is easy and fast to use it for IoT projects and integrate it into Google Assitant very fast. Currently, I am using ESP RainMaker cloud on a project, I want to also integrate it into my custom app that I will be creating using flutter but I am currently having a problem with using the API connection of the ESP RainMaker. After entering the Auth keys and everything still, there is no communication. The response I always get is a failure.
So please I wish you can do a video explaining how to use the RainMaker API for custom Apps and websites. I know you are very good at IoT and hope to hear from you soon.

Sir, can you help me about esp32 ULP with arduino IDE. There are a few examples, but too confusing for beginners like me.

[rarenu]

Please share the code in your link as it is not there in the link shown.

[hasstv]

I'm getting
Claiming failed with error : Claim init failed
error in the app, after scanning the qr code. it never happened before.
Someone please help me.

Shall I use this PWM signal using to start bldc motor control system....

Using this pwm to give input for a driver circuit



Is it possible? Sir

Hello Folks, I just found out there are only 5 devices allowed on rainmaker. Has anyone encountered this issue! Please advise

[djokinac]

Hello
I have a request for you
please help me if you can

I live in a forest and have my own electricity from solar panels and from a small turbine on the stream

I should check the voltage from the turbine on an esp32 pin and if the voltage starts to rise, I should include a strong waiting resistor on a pwm pin to slow down the turbine if the batteries are charging, all this can be seen on the esp rainmaker

my level of knowledge is only copy paste unfortunately

I thank you in advance for your time and effort
