2x LiPO Battery to 12V and 5V Converter
This board provides 12V/200mA DC and 1.2V to 6V/500mA DC Adjustable output with input of 7.4V 2x LiPO batteries. The board is a step up DC-DC Convert based on CS5171 and LM317 adjustable regulator. The Step up DC-DC converter provides 12V DC from 7.4V ( 2x LiPO batteries) and LM317...

Electronics has transited from a work meant for well-trained engineers to something which is dabbled into by people in other fields especially in Arts and related fields. The introduction of platforms like Arduino (which was created for reasons like this), has been one of the main...

Voltage is one of the fundamental values when dealing with electronics. It determines the amount and direction of current flow and represents the potential (electric charge) difference between two points, thus it is somewhat impossible to build or troubleshoot electronics circuits without...

Fingerprint sensing is one of those technologies in science fiction movies that fascinated most of us as kids. Today, they are everywhere and asides from existing in everyday devices with huge electronics complexity, like mobile phones, they are also available in tiny modules to give...
Continue ReadingUsing the Arduino IDE’s Serial Plotter Feature
Visualizing data when working with the Arduino is something we all have had to do using third party/ self-developed software in the past. It was thus, it is really interesting when the Arduino team decided to change that recently. Today, we are going to take a look at their solution,...
Continue ReadingUsing the ILI9481 3.5″ Color TFT Display with Arduino
Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today's tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino. This...
Continue ReadingUsing the 433MHz RF Transmitter and Receiver with Arduino
Introduction While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where...
