In this article we will see how to interface Arduino with the LoRa module E32. LoRa stands for Long Range. It uses license-free sub-GHz RF bands for operation. These bands are different in different countries. In India, the permissible band is 865-867 MHz. LoRa is very ideal for IoT applications ... Read More

Zigbee is a wireless communication protocol targeted for battery powered devices (it has both low power and low cost). It generally operates in the 2.4GHz range (although there are geographic variations), and supports data ranges from 20 to 250 kbits/s.The transmission distance though, is small compared to the likes of ...

Queue is a data structure that helps exchange data between different tasks or between tasks and interrupts. It holds a finite number of items (defined at the time of initialization) and operates in the FIFO mode.We will walk through an example that comes in with the FreeRTOS library, to understand ...

The isGraph() function is very similar to the isPrintable() function in Arduino. The only difference is that isGraph() returns true only if the character being printed has some content.So, blank space gets excluded by isGraph() but included by isPrintable(). All normal characters, numbers, special characters, which have some content will ... Read More

shiftIn() and shiftOut() commands in Arduino are, very loosely speaking, software implementations of SPI. Of course, SPI is much faster, but SPI can work only on some specific pins of Arduino. shiftIn() and shiftOut() can use any two GPIOs of Arduino (not some specific pins like SPI).Both shiftIn() and shiftOut() ...
