DIY Hand Sanitizer Dispenser Using Arduino 14 Steps with Pictures Circuit Diagram An automatic hand sanitizer dispenser is automated and alcohol based the most important criteria is that it is touch-less machine, which will be used in hospitals, schools, work places and much more. The electronic hand sanitizer dispenser is based on IC 555. Our sensor-based automated hand sanitizer dispenser senses the ambient light intensity too. When the light emitted from LED on the LDR obstructed by the hands, the resistance of LDR is increased. The LDR along with sensing element 1M potentiometer is connected to 2 and 6 pair of IC 555. In this project, we create a contactless hand sanitizer dispenser that can be used for any press-to-release hand sanitizer available in the market. The project uses an Arduino Uno, an HCSR04 Ultrasonic sensor, and a servo motor. The system is adjustable to accommodate most sanitizer bottles.
I built a motion-sensored automatic hand sanitizer dispenser using a 3D printer and coding to combines and practicality and an easily functioning device. Why I built this device was wanting to create something that could be used in a classroom or professional setting that is especially needed in stopping the spread of germs within public spaces.

Practical Applications of an Automatic Dispenser. Here are some use cases where automatic dispensers are widely used: Hand Sanitizer Dispensers: Essential for hygiene in homes, offices, and public spaces. Soap Dispensers: Commonly used in restrooms for touchless operation. Food Dispensers: Ideal for dispensing pet food or grains.
To design an automatic hand sanitizer dispenser, first, we will need a container to store soapy water. After that, we will need something that will pump soap water and this thing is a DC water pump. The DC water pump will pump out soapy water for us.

Structure foreground. 2. Controller Design. As seen in Figures 4 and 5, the Automatic hand sanitizer device consists of a power supply, sensor, board, motor controller, and motor.The power supply provides voltage and current for the operation of the motor and board, and its power source is a battery.
