Development of Smart Recycle Bin using Microcontroller

by NOR HABSAH OTHMAN
Supervisor: Madam Azliza Binti Mohamad Arshad

Synopsis of the project: Smart recycling bin serves to sort three types of waste ie metal, paper and plastic. It uses a microcontroller and sensor to detect the type of trash and the main circuit is powered by power supply.

Week 1
