Arduino & Raspberry Projects
2 Channel High Current Arduino Relay Shield
2 Channel Relay Shield for Arduino UNO is a simple and convenient way to interface 2 relays for switching applications in your project.
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.
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.
Using 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.
Using 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 communication is one way (Receiving device cannot transmit and the transmitting device cannot receive).
Arduino Real Time Clock and temperature Monitor using the DS3231 RTC and 3.2″ Color TFT display
Time is a critical element of our existence that will never get old, and with technology, we can find better and more intuitive ways to measure it.
Getting Started with the NodeMCU (ESP8266 Based Development Board)
As the popularity of Arduino boards increased, the demand for boards which comes embedded with some of the add-ons used with the Arduino increased.
Programming Atmega328p Microcontroller with Arduino IDE
Introduction Over the past few tutorials, we have mentioned several scenarios where using any of the Arduino board in a project may be an overkill due to the cost, size, and more technical reasons such as high power consumption.
Flashing Arduino Bootloader on Atmega328p Microcontroller
Introduction Cost and size, just to mention a few, makes using an Arduino board in certain projects an overkill, often times its always too big, or too expensive for the scope of the project especially when it’s a project that we need to make several units.
Automatic ON/OFF Power Switch For Arduino
Over the past few tutorials, we explored several ways to further reduce the power consumption for Arduino based projects so they can last for a long period of time running on the inexpensive AAA batteries.
Communication Between Two Arduinos Using NRF24L01
While building Arduino or any other microcontroller platform project over time the need will arise to establish communication between two of the Arduino boards or microcontrollers for data exchange and/or control.
Low-Power Arduino Weather Monitoring Station
Introduction One of the downsides of using an Arduino board in projects is the fact that it comes with some other components which may not be needed after the code has been uploaded to the board.
