Connecting a Servo Motor to An Arduino

Arduino Servo MG996R

Building robots with Arduino starts with knowing how to move objects through motors. There are a lot of types of motors used in microcontroller-based systems: DC motors, stepper motors, and servo motors.  In this Arduino servo motor article, I will discuss what is a servo motor and how to use …

Arduino Like IDE for PICs

arduino like ide for pic - chipkit uc32

Before the Arduino became popular, PICs were the go-to microcontroller device for most electronic hobbyists. PICs were cheap and the resources (at that time) were plenty. But then Arduinos came, which offer a much simpler way to code and so only a few now use these microcontrollers. Arduino’s strength relies …

Intro to NodeMCU and Arduino IDE

node mcu v1.0

The NodeMCU is a development board featuring the popular ESP8266 WiFi chip. As it turns out, you can program the ESP8266 just like any other microcontroller. Its obvious advantage over the Arduino or PIC is that it can readily connect to the Internet via WiFi. However, the ESP8266 breakout board …

How to Manipulate Arduino Pins Simultaneously

Arduino Pins Map

If you’ve coded PICs before Arduinos one of the things you might have noticed is the lack of function on the latter to manipulate multiple pins at once. Manipulating all the Arduino pins at once is needed, for example, when using a seven-segment display or creating strobe lights. Is there …
