Communication
SPI vs I2C
When it comes to sensors and shields, two common serial connections available are SPI and I2C, but what exactly are they? Serial Peripheral Interface (SPI)…
Wired Communication Protocols: SPI
For the final part of the wired communication protocols series, we are going to discuss SPI, also known as Serial Peripheral Interface.
Wired Communication Protocols: I2C
So far we’ve talked about wireless technologies and UART communications. In this tutorial, we will talk about Inter-Integrated Circuits or I2C. I2C I2C (Inter-Integrated Circuits)…
Wired Communication Protocols: UART
In this new series of articles, we are going to explore wired communication protocols. It will consist of 3 parts, starting with this one for…
Wireless Technologies for Your Arduino Projects
Circuitrocks has a bunch of wireless technologies available for Arduino wireless communications. Here is a short guide on how to choose the correct one for…
Alora RFM1262 – LoRa Mesh Network
LoRa is a wireless communication known for its long range capability. But what if the distances between sensor nodes are farther than the range you…
ESP32 LoRa gateway battery optimized

Long Range (LoRa) communication for devices that have no WiFi connection available
Usually we use WiFi, Bluetooth or GSM to connect our sensor devices with the world of IoT. But what if neither of that is available (or not affordable like GSM)?
