Acquire the ability to switch ON/OFF (and mute) TV by voice command via Amazon Echo.
Project showcase by LIMPINGLIM
Customised solar-powered & sensor-controlled guard lights to brighten up my apartment balcony that somehow does not have any lights fitted.
I was commissioned to create a quiz buzzer that would be used in a video shoot.
A volume control for the TV/receiver using Arduino Nano.
3D-printed enclosure makes it look lite Amazon Dot.

Yes, it's overkill, but if walking up motion-activated light-up stairs is wrong, well then I don't want to be right.

You ever lose your clicker/remote and wish you could just talk to your TV? Well anything your clicker can do, your Alexa can do!

Thanks for your comment/question.
I also thought about putting everything on one board & my first attempt was with a Wemos D1 R2 board but it somehow didn't work. I'm not very sure which part of the coding I was missing (as coding is not my strength & maybe the board I'm using is a cheap clone?).
For the time being, I plan the esp8266 to only work as the link between the Amazon Echo and the Nano board. I believe if the code is too long in the esp8266, it'll slow down its response to voice-commands as well? Also, in the near future, I intend to expand the functions on the Nano board to include elements such as temp/humidity sensing to control my portable evaporative cooler, just in time for the dry summer heat in Australia.
Well, if you have an improved approach, I'm sure a lot of people (including me) would be happy to expand on your idea.
Please note that the actual (large) 7-segment display used in this project requires around 8V to work. The final wiring differs from the simulation digram on Tinkercad. The online simulation platform only provides small 7-segment displays which runs on lower voltages and can be connected directly to the digital outputs of the Arduino with the appropriate use of protective resistors.
