NodeMCU Voice Bin Lid
Just .. out .. of .. reach. The solution is of course to waste additional resources bcz what is it to be modernly alive if not burdening others, from the unseen to those cherished. To hell with them all bcz the bin is aesthetically more appealing out of reach.


Ingredients
NodeMCU
MG995 Servo
3D Printed Bits n' Pieces
Adhesives
Voice Attack (software)



Notations
1. This project was least about creative thinking and more about episodic novelty practicality .. a form of selling out .. in my mind.
2. The feisty bot is K∞e (pronounced Katey). She/it will co-star in several upcoming engineering episodes bcz she/it does not demand scale.
3. The code presented features both the trash bin lid and a light switch relay.
4. Program voice cmd to call url http://192.168.0.47/trash -> or go to url and press 'trash' button.
