Making a Media Tower with Pop up Projector and Sound Bar.
Here is an easy project using a Echo Dot (Alexa) to control my ESP8266. I give it simple commands (Alexa, lights, off) and the command shows on the LCD screen attached to the ESP8266. Actual relays will be the next step to attach.
The project is based on the Adafruit tutorial at https://learn.adafruit.com/easy-alexa-or-echo-control-of-your-esp8266-huzzah/overview
with LCD and other modifications made by me. My code is found at https://pastebin.com/NjMcsTRh
You surely know this feeling when the doorbell rings while you are doing something interesting: watching a movie, playing a video game, or spending a romantic evening with your loved one. And when it turns out that this is an uninvited/unwanted guest, you get even more pissed off.
Of course, you can ignore it and not open the door, but there will always be this hint of uncertainty – “maybe it was important”.
The solution to this problem is the “smart doorbell”. Thanks to it, you’ll know if it is worth getting up from the couch and opening the door or not.
Today I would like to propose a simple project that requires easy skills. It’s a simple weather station, that measures, internal and external temperature. It’s made out of two components: an indoor receiver, and an outdoor transmitter. The transmission is managed at 433Mhz. The components and the electrical diagram for both devices, are showed in the video. The receiver is very easy to use. to toggle between the external and internal temperature, you need to press the button for more than 3 seconds.
Automated lightening of staircase not only helps to save electricity but also takes us to advancement in quality living of life. We generally uses normal circuit to turn on and off the light in stairs, but there is loss in electricity since we turn it off only at once during sleep. So, in this tutorial we are going to make the automated staircase that will light up only when it senses motion of people passing through stair.
In this tutorial I am going to show you how to build your own access control system with RFID and Arduino + Cloud logging of attendance.
It is a very good project for IoT beginners and enthusiasts, hope you like it.
This is how used a nodeMCU to automate electric appliances
This is a smart home kit from Keyestudio. It’s a really fun way to learn Arduino.
We’ve been building towards this project in the previous set of videos. And we’re now ready to build our very own DIY Alexa!
