Abstract

These blind people still have difficulties in carrying out their activities, especially in terms of mobility in society. This is of course due to the lack of facilities and infrastructure that can support blind people in carrying out their daily activities. One of the assistive devices commonly used is a blind cane. With this stick, blind people are quite helped, especially when walking, but the conventional cane has limitations, one of which is the reach is too short. Thus, in this study, a concept for walking aids for blind people was developed by designing a new device that can cover the limitations of conventional canes. The tool is designed to utilize microcontroller technology with a minimum Arduino uno system, ultrasonic sensor HC-SR04, and DFPlayer Mp3 Mini module. The results showed that the designed tool can detect a maximum distance of 80 cm and can make a sound when the ultrasonic sensor is blocked.

Abstract

In general, sorting waste is still done manually by human hands. For example, it is still done manually by human hands to sort metal and non-metal waste from a pile of garbage. This results in less efficiency in terms of time and energy and also greatly impacts the health of oneself and others. With these conditions, one solution is to build a metal and non-metallic waste sorting system in the trash. The metal and non-metal waste sorting system that is made can sort metal and non-metal waste automatically because it is equipped with an inductive proximity sensor system which functions to detect metal waste plus a NodeMCU module which functions as a data sender of information on the weight capacity of the waste. With this automatic waste sorting system, waste can be sorted according to predetermined types of waste such as metal waste and non-metal waste.
