Water is a fundamental need for humans, comprising 70% of the human body. Dispensers are commonly used due to their convenience and hygienic nature for storing drinking water. Visually impaired individuals often face challenges in using conventional dispensers, which can lead to injuries when retrieving water. This study aims to design an automatic dispenser to assist the visually impaired, reducing the risk of injury when using dispensers. The dispenser is designed with two microcontrollers: Atmega32 and ESP8266. The ESP8266 microcontroller has a Wi-Fi feature, enabling it to connect to the internet. The dispenser uses two ultrasonic sensors to detect objects obstructing the sensor’s beam, helping control the flow of water. The system communicates between the two microcontrollers and connects to the Telegram app via Wi-Fi, allowing for remote monitoring and control. The Arduino Uno microcontroller serves as the system’s control center.
