For those who are looking to work with images on their projects, the Raspberry Pi offer enough tools to work with. This short tutorial will guide you on how you can take pictures using a camera attached to your Pi and then upload those camera images for use in a …

A Raspberry Pi HAT is a circuit board placed on top of a Raspberry Pi in order additional features to the single-board computer. There are a lot of Raspberry Pi Hat available for purchase. This post will show you how to build your own Hat.

The emergence of the ESP8266 WiFi module has allowed makers and enthusiasts to create Internet-enabled projects at a minimal cost. Moreover, the popularity of the module also gave rise to commercial boards like the NodeMCU, WeMos D1, Adafruit’s Huzzah. Sparkfun’s ESP8266 Thing and many others. Practicality would make you just …

Vias are very common when designing PCBs. I myself have used PCB via even before fully understanding them. In this article, I will be sharing the different types of vias and how they are actually used in PCB design.

In the past, I used to build project prototypes through breadboards and perfboards. However, the emergence of affordable PCB manufactures have allowed me to go away from my old ways of prototyping. In this article, I will share how I created the PCB board for my SIMPic development board through …

I always believed that the Arduino is a development board and is its microcontroller, the ATMega328 is the one meant to be featured in actual embedded systems projects.  Nevertheless, no one can deny the advantages of boards like these as they make prototyping and debugging much easier. In this post, …

In general terms, a magnetometer measures the magnetism of objects or places. In fact, a compass is a type of magnetometer. This project demonstrates how to use the HMC5883L magnetometer IC as a compass with an Arduino microcontroller.

The PIC16F877A microcontroller comes with a Capture Compare PWM (CCP) module which utilizes its 16-bit Timer1 module to generate or count pulses, among other things. I have already covered how to generate PWM in my previous tutorial. This time, we will look at how to implement capture and compare with …

This project demonstrates how to read data from the DHT22 temperature and humidity sensor and send that data to the web using an ESP8266 via MQTT.

Last time, I showed how to get started with Microchip’s Curiosity HPC board. I will now explore the use of the included buttons and LEDs on this microcontroller board.
