Automatic Hand Sanitizer (Arduino)

thingiverse

Special for this time around! We all mess up with COVID-19 Pandemic and want to Sanitize our hand regularly. We have the Sanitizers in a bottle? Put an Arduino on it and make it Auto Spray with a Servo! The Automatic Hand Sanitizer utilize 2 size of bottle > that have average neck diameter of 24mm and 32mm. I think both of this bottle is quite common in Malaysia and maybe around the world. Parts Needed to complete: Arduino Nano without leg is preferred. https://www.aliexpress.com/item/32341832857.html?spm=a2g0o.productlist.0.0.5ec74442BQvMX8&algo_pvid=be03587b-a23b-491d-aec8-98b34cc0e109&algo_expid=be03587b-a23b-491d-aec8-98b34cc0e109-0&btsid=0ab6fa8115876613418444299ee993&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ https://shopee.com.my/Arduino-Nano-V3-Without-Cable-Unsoldered-CH340G-Atmega328P-Atmega-328P-328-P-i.13050358.6519792105 HV Micro Servo capable of 7.4Volt https://shopee.com.my/Inservos-Digital-7.4v-3.6kg-Metal-Gear-Micro-Servo-D0474HT-HV-i.23419821.1438895359 https://sea.banggood.com/Inservos-D0474HT-3_6kg-7_4V-HV-Metal-Gear-Digital-Micro-Servo-p-1037361.html?akmClientCountry=MY&&cur_warehouse=CN https://www.rchopez.com/webshaper/store/viewProd.asp?pkProductItem=2087 Servo Extension. https://www.rchopez.com/webshaper/store/viewProd.asp?pkProductItem=3908 https://shopee.com.my/Servo-Extension-Cable-3P-(100cm)-i.40459773.1473325148 IR Sensor for Arduino https://www.aliexpress.com/item/32716407598.html?spm=a2g0s.9042311.0.0.27424c4dI5Vctf https://shopee.com.my/-PROMO-Diffuse-Sensor-FS80NK-5V-NPN-Hot-for-Sumo-Robot-!-i.242730221.3429173921 Battery 2 Cell Lipo (Small Size 450Mah) https://www.aliexpress.com/item/33017993913.html? spm=a2g0o.cart.0.0.466a3c00fL5yf6&mp=1 Installation Video. https://youtu.be/PAj4wJ-QM0c
