Arduino IF Statement Code Examples by Lewis Loflin Video for this page: Arduino Comparison IF Operators Think of a micro-controller as a box full of basic logic circuits, gates, etc. To control the "box" we have to tell it what hardware to use. We must tell the "box" how to manipulat...
After that we will see the general concepts of interrupts. We will see how to use interrupt service routine with Arduino. At the end of article, we will take two examples to demonstrate the effect and use of Arduino projects in real world embedded systems projects. Arduino programming getting ...
However, additional features of ESP32 WiFi and specific protocols can be accessed through external libraries that we’ll need to install as we go further with the example projects. Given that the ESP32 WiFi library is already in Arduino Core, the next step will be to include it in your ...
In this tutorial, you’ll learn about ESP32 PWM and how to control PWM channels in Arduino Core. But first of all, you’ll get an introduction to what’s PWM and how it works in most microcontrollers on a hardware level. Then, we’ll investigate the ESP32 PWM Hardware peripheral and ...

ULN2003 and 28BYJ-48 to Arduino Connections Please note: It is possible to directly power the stepper motor from the 5 V output of the Arduino. This however, is not recommended. When the stepper motor draws too much current you candamage the Arduino. I also found that when powering the ...
Connecting a DS18B20 to the Arduino is fairly easy as you only need to connect 3 pins. Start by connecting the GND pin to ground and the VDDpin to the 5 V output of the Arduino. Next, connect the middle pin (DQ) to any of the digital pins of the Arduino. In this case, I used...
Example 1: Basic Arduino setup This is the most basic example you can have with an Arduino, an Easy Driver, and a stepper motor. Connect the motor's four wires to the Easy Driver (note the proper coil connections), connect a power supply of 12V is to the Power In pins, and connect...
Arduino Analog Read Pins Analog pins in the Arduino board are marked with the letter ‘A’ e.g. a0, A1, A2, A3, A4. That means it has 5 built-in analogs to digital converter channels. Only these analog pins of Arduino can be used to measure analog signals. But If you want to use...
