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.

As a lifelong PIC fan, I was super thrilled when Microchip sent me a free unit of their Curiosity HPC development board. I’ve been working on PICs for years by just mounting them on breadboards and using PICKit to flash programs. This takes time and so when I’m faced with …

This project demonstrates how two Bluetooth modules connect with each other. I’ll be featuring DFRobot’s Input Shield V2 as the transmitter/controller and Seeed’s ShieldBot, which was seen on my Bluetooth RC Car project, will act as the receiver.
