HariFun #125 - Internet of Things in 5 minutes!

The ESP8266 has really come a long way since AT-commands.

That looks really fun man . great video, and love the stop motion intros. I'll have to have a boo at the Adafruit IO stuff when i get a day this week .

Thanks Hari for the video.
Great way to gain IoT experience without spending a lot. Before it was Ethernet shields or Xbee modules . . . @ 4x the cost.
Also, nice video production job with just the right amount of detail.
Good reason to dig the old X10 modules out of shed. And those old (D.C. Hayes modem) AT commands . . . from the early 80's, yes we have evolved.

Thank you so much! This was very informative. Now i need to learn about MQTT lol. Time to find a video.

This is helpful...One comment -- the DHT constructor did need a third parameter with a integer value (like 10 or 15 -- I put 15) to account for the speedy processor ESP8266 compared to Arduino UNO (for which the library was intended as default). Adafruit library does have details on this in the comments.


ON the whole, thanks for a great prez.

Thank you, Hari. I stumbled across this video and it has me excited to purchase the right stuff and dive in. What items/products do you recommend for someone to immerse themselves?

See, I thought with installing the arduino firmware, you were basically turning it into an arduino, which would basically disable the wifi capabilities. Shows you how much I know. Hair, do you have any straight forward all encompassing sources on learning about NodeMCU or ESP8266? I've been reading and researching, the info is scattered all over the place. I guess it's best to just jump in and start programming. This looks like a good start. Thanks Hari.

Thank you for the vid and the hint for using Alexa with ifttt.
Currently I am testing a recipe from weather.com to work as a timer for outdoor light when sunset on and off when sunrise but still I didn't program the ESP. It is working on the dashboard as it should.
Adafruit.io is great.

Hi Hari - fantastic video! Bit confused about how to sign up with adafruit for IO service you are using? Do I have to sign up and create a normal account as if I was going to purchase something online to use the IO and dashboard facilities or is there some other way I have to sign up with adafruit??? Just a raw newbee to this area of electronics and this part of the process is a bit confused  with every thing else that is on the adafruit web site! Cheers, Ian

Hari, did you have to flash a different firmware to the ESP before you could upload an arduino sketch? I'll be getting NodeMCU which comes with LUA.

Nice video!
Im trying to set this up to use with an UNO (need more Inputs) and the 8266 connected through serial.
I keep getting this error when i compile :

fatal error: memory: No such file or directory
#include <memory>

Do you know what the issue is?

Hi, Hari... :)
You seems to indonesian people..
I'm new in esp, but can i ask some questions?
Please help me..

I want to connect "two ESP8266" through internet via wifi. So, is it possible to connect them both?
For example,
- The first ESP act as transmitter, and the second is receiver.
- I put one or two push button in my first ESP (on-off), and one potensiometer (adc).
- Then, my idea is those input can controlling my second ESP. The output may be relay, or led..
- When i push the button from first ESP it can trigger the relay in second ESP to turn on or off.. Or when i turning my potensio, it can dim the led.
All this time, i have searched the solution but not found, evenly they show how to send data sensor from ESP to web server like thingspeak etc. Or from webpage they can make an interface to controlling device like ON-OFF..

So Hari,
Can you give me some advice to open my mind?
What is needed?
OR can you tell me the plot?

i dont get the adafruit why are you using that
