Before we start, please note that most Apple devices don’t support the virtual serial link profile that these modules use. A really easy method of making your projects wireless is to use serial Bluetooth modules, these modules take standard serial data and transparently transmit it via Bluetooth to another connected Bluetooth module, no extra code …

The nRF905 is a radio transceiver IC similar to the well known nRF24L01, but operates at 433/898/915MHz instead of 2.4GHz, has a much longer range and a few extra IO pins. However the nRF905 data rate is only 50Kbps compared to nRF24L01’s 2Mbps. This library offers quite a bit of flexibility: Optional use of interrupts, …

I had been eying up Arduinos and looking into getting started with digital electronics for a while and now finally brought an Uno along with a 16×2 character LCD with RGB backlight. Wow. It’s like I’ve unlocked a whole new world of electronics, for years I’ve looked at digitally controlled devices like LCDs woundering how …
