Arduino UNO R4 では、これまでの8bitのATmega328から、32bitのArm Cortex-M4プロセッサへと、大幅なCPU性能の向上が図られました。ルネサス製RA4M1という日本のメーカーのCPUが採用されたという点でも喜ばしいことです。 今回は、Arduino UNO R4に1.5inch OLEDモジュール (waveshare製)をSPI接続して、デモ用の ...

This module operates under a supply voltage of 1.9V to 3.6V and consumes only 13.5mA of current and in deep sleep mode, it consumes 26uA. One very interesting fact of this module is that the SPI pins ...

It is a communication library that allows two Arduino’s to communicate with each other using RF Module i.e. transmitter – receiver pair. This library consists of several functions that are used for ...

Arduino-RF-NRF24L01-Comm Arduino includes RF communication applications using the NRF24L01 module. The NRF24L01 module is connected to the Arduino. These applications are: Master and Slave.

I previously featured XBee-PRO 900HP RF Module with a 45km range, so the Semtech module is just another option, and it works not only with Waspmote, but also the Raspberry Pi, Arduino, and Intel ...
