NRF24L01 Based Wireless Weather Station with DHT22 and 3.2″ TFT display
While IoT is awesome, there are situations where we do not necessarily want to connect the devices to the internet but connect them together. It could be a need for a local network of sensors to monitor certain parameters on a farm for instance. This kind of project will involve a base...

Arduino DIY Photo Frame using ST7735 1.8″ TFT Display
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...

DIY Arduino Uno LCD Voltmeter
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...

Using an Optical Fingerprint Sensor with the Arduino
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...

Using 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,...
