Using the 433MHz RF Transmitter and Receiver with Arduino

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).

Programming Atmega328p Microcontroller with Arduino IDE

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

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.

Low-Power Arduino Weather Monitoring Station

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.
