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 as a compass with an Arduino microcontroller.
Read More »Capture and Compare with PIC16F877A
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 …

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 the board.
Read More »First Use of Microchip’s Curiosity HPC
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 …

The DHT22 temperature and humidity sensor is a common sensor; in fact, there are tons of tutorials out there teaching you how to use it with your Arduino, Raspberry Pi or other microcontrollers. What prompted me to write about this sensor is my curiosity on how it gives out two …
Read More »Obstacle-Avoiding Arduino Robot
To kick off 2019, I would like to create a series of Arduino Robot projects that anyone can learn how to build. The first part of the series is the popular obstacle-avoiding Arduino robot.
