How To Build an Automatic Hand Sanitizer Dispenser

Corona virus is a very deadly virus that is claiming the lives of thousands of people globally. It started in Wuhan, China and quickly spread to rest of the world. Currently at the time of writing this post there is no known cure of the virus, however there are ways of reducing the risk of infection. Among the ways is the use of alcoholic hand sanitizer which will greatly reduce the risk. Other measures against corona are listed here. Hardware Requirements The hardware component required for project are; Microcontroller (Arduino uno) Proximity Sensor Mechanical Valve Power Supply Liquid Container Relay Module Arduino Uno is not the best micro-controller/ development board… Read More

Ever wondered what is an Arduino? Or are you a maker who is thinking about moving on to the Arduino platform? Which ever your situation this article will get you up and going. WHAT IS AN ARDUINO Arduino is an open source development platform for electronics based on the AVR micro-controllers. It features a simple hardware and software layout. Its products are licensed under the GNU lesser General Public License (LGPL) and the GNU General Public License(GPL). This means that the manufacture of Arduino boards and software distribution by anyone is allowed. Arduino boards are available commercially in preassembled form or as do-it-yourself (DIY) kits. The Arduino LLC has a… Read More

Hello there and welcome to this blog post about how to build a  simple 5v power supply, Most electronic component, logic circuits and micro-controllers/processors require a clean and stable 5 volt power supply to work, some may be flexible to work with a range of voltages; say from 4v to 13v, whereas others are a bit sensitive and choosy they require 5v with little to no tolerance, so one has to be careful of what he is feeding his device To build a stable power supply there are many topologies to consider this will greatly go a long way in determining the size, cost, reliability, and speed of production the… Read More
