Introduction: Smart Segregator/Dustbin
Smart Segregator/Dustbin talks to you when you approach it and helps you choose the correct options to throw your waste. In our version it first speaks in english and if you stand around longer it will speak in Konkani (Goan Language). The moment you move away it says thank you and shuts up. And we made the smart segregator separate from the dustbin because then you could put it in front of any 3 standard public dustbins as well.
Step 1: Components
Step 2: Circuit Diagram
Step 3: Adding Required Arduino Libraries
1) New ping library
ultrasonic sensor (HC-SR04) are used to detect the presence of human beings in front of the dustbin.
new ping library is used.
2) DFplayer mini library
DFplayer mini is used for playing the required the audio.
Step 4: Preparing the DFplayer Mini
All the 8 audio are added to micro sd card and inserted into the DFplayer mini.The audio names should be 0001, 0002, till 0008.
connect a drive speaker less than 3W to pin spk1 and spk2 pin of DFplayer mini.
Step 5: Code
Upload this code in arduino.
We have a be nice policy.
Please be positive and constructive.
