The Raspberry Pi Zero W comes with both WiFi and Bluetooth connectivity. I have already covered how to turn on WiFi on my previous tutorial. Now, let’s look at how to set up a Raspberry Pi Zero bluetooth connection without a GUI.

A water level sensor is a simple device used to measure the level and volume of water inside a container. This tutorial shows you how to use a water level sensor with microcontrollers like an Arduino or PIC.

LoRa is a promising low-power, long-range wireless transmission protocol developed by Semtech as part of the emergence of the Internet of Things (IoT). Simply put, it is a method for sending data separate from WiFi, Zigbee, or Bluetooth. Its low power consumption amidst a very long range of transmission (up …

The number of Arduino boards have increased over the years; some have been discontinued while others are still available. The choice of which board to use depends on several factors: price, features, availability, ease of use, etc. Here’s a summary of all Arduino boards with their pros and cons.

For the next part of my series on PocketBeagle, I will show how to add WiFi connectivity to the board. This board doesn’t come with built-in WiFi like the Raspberry Pi Zero W. With a simple hack, I managed to add WiFi connectivity to it.

A flex sensor can be used with a microcontroller to detect or measure bending.  In this tutorial, I will show how to interface this sensor with an Arduino UNO and discuss some possible flex sensor applications and projects.

The MQ-6 is a semiconductor gas sensor device for detecting the levels of propane and butane in the air. Since liquefied petroleum gas (LPG) is composed of these two gases, then the MQ-6 can be used as a LPG sensor.

I am a fan of the BeagleBone Black. Thus when I heard that a small-body version of the BBB is now available, I purchased it immediately even if it costs twice as much as the other small-body SBC, the Raspberry Pi Zero. The PocketBeagle, as it’s called, also doesn’t have …

Last year, both Raspberry Pi and Beaglebone Black released mini versions of their popular microcomputers: the Raspberry Pi Zero and PocketBeagle. I happened to own both and had a chance to compare. Which small-size single board computer (SBC) is better? It’s Raspberry Pi Zero vs. PocketBeagle after the jump.

You can in fact build your own motion sensor without spending too much. Motion sensors can be set up using ultrasonic transceivers, video cameras, or microwave signals. In this tutorial, I’ll show you how to use the PIR motion sensor with a microcontroller. PIR is short for passive infrared which …
