A portable variable voltage/current power supply
Working on my portable power supply for my electronics project with a variable constant current/voltage feature plus fixed settings accessible with a press of a button.

This tiny power module can be used as a “UPS” for IoT projects. You can connect both an ordinary 5V mobile phone charger and a Lithium battery to provide a continuous 5V supply to simple projects.
When you are dealing with electronics, component temperature will always be a factor. An infrared thermometer is very handy in cases where you would want to know if the temperature is within the component’s specified operating range.
The LM317 chip is an adjustable linear voltage regulator that you can use to provide power to your electronics project. It has a range of 1.25 to 37 volts and offers a maximum current output of 1.5 amperes.
After writing an article about batteries, I thought it’d be great to write something about displays/screens that are available for electronic projects — especially small ones before going into detail on each of them at a later article.
Recent miniaturization of electronic components not only bring smaller projects but also less power hungry ones. We now have pocket computers that do in seconds what room-sized computers do in a day — powered by batteries to boot.
In my opinion, the ESP8266 actually gave birth to the Internet of Things (IoT). The inclusion of an integrated WiFi electronics changed everything — it gave the ability for single chip computers like the ESP8266 to connect and communicate with other computers.
Electronics projects that I want to do most of the time need either a 5V or 3.3V supply so I decided to buy one of those off-the-shelf Breadboard power supply.
When you’re trying to solder things together, it really helps to have more than just two helping hands besides my own… and with parts getting smaller the magnifying glass (or an iPhone camera) is your friend
A basic thing that is called a solderless breadboard is where it all begins. A tool that allows different electronic components to be connected together and perform in synchrony to do different tasks. It can be something as simple as turning on/off a light.
