Getting Started with MIT App Inventor 2 and Arduino

In this post I’m going to introduce you to the MIT App Inventor 2 software and I’m going to show you what you need to quickly getting started building Android apps that interact and control your Arduino.

Gesture Slider Swiper with Arduino

This project was written by Emmanuel Odunlade and edited by Rui Santos. In this post you’re going to learn how to set an Arduino UNO board as a USB HID keyboard and use gestures to swipe slides during a presentation.

Build a Night Security Light with Arduino

In this project you’re going to build a night security light with a relay module, a photoresistor and an Arduino.

Door Status Monitor using the ESP8266

In this project you’re going to monitor the status of a door using an ESP8266. The goal of this project is to show the endless possibilities that this $4 WiFi module offers when integrates with a free platform that I’m about to show you.

Arduino – Control 2 DC Motors Via Bluetooth (Perfect To Build a Robot)

In this tutorial I’ll show you how to control 2 DC motors via bluetooth with an Android app created with MIT App Inventor 2. MIT App Inventor is a great platform to get you started with Android development.

Guide for TCS230/TCS3200 Color Sensor with Arduino

This post shows you how to detect colors with the Arduino using the TCS230/TCS3200 color sensor. The TCS3200 color sensor can detect a wide variety of colors based on their wavelength. This sensor is specially useful for color recognition projects such as color matching, color sorting, test strip reading and much more.

Build Robot Car Chassis Kit – Arduino

In this post you’re going to learn how to build a robot car chassis kit that is commonly used with the Arduino board. You can either watch the video tutorial or follow the written instructions. Throughout this post, we’ll be assembling a Smart Robot Car Chassis Kit that can be found on eBay.

ESP32 Web Server – Arduino IDE

In this project you’ll create a standalone web server with an ESP32 that can toggle two LEDs using the Arduino IDE programming environment. If you want to learn more about the ESP32 dev board, read my Getting Started Guide with ESP32.

Arduino Ethernet Web Server with Relay

This posts shows how to build an Arduino Ethernet web server that controls a relay that is attached to a lamp. You can access your web server with any device that has a browser and it’s connected to the same network.

9 Biometric Sensors Arduino Compatible

In this post I’ll share with you a list of 9 biometric sensors Arduino compatible that you can use in your bioengineering experiments. These are great for hobbyist projects since most of them are easy to deal with. Here’s the list:

ESP8266 OTA Updates with Arduino IDE | Over the Air

OTA (Over the Air) update is the process of loading a new firmware to ESP8266 module using WiFi connection rather than a serial communication. This type of functionality is extremely useful in case of no physical access to the ESP module.

Getting Started with ESP32 Dev Module

This is a getting started guide for the ESP32 Dev Module. If you’re familiar with the ESP8266, the ESP32 is its sucessor. The ESP32 is loaded with lots of new features the two most important: it combines WiFi and Bluetooth wireless capabilities and it’s dual core.

Installing the ESP32 Board in Arduino IDE (Mac and Linux instructions)

The ESP32 is currently being integrated with the Arduino IDE just like it was done for the ESP8266, but not everything is working at the moment (see here). This add-on for the Arduino IDE allows you to program the ESP32 using the Arduino IDE and its programming language. If you like the ESP32, you might also enjoy reading all my ESP8266 […]

Installing the ESP32 Board in Arduino IDE (Windows instructions)

The ESP32 is currently being integrated with the Arduino IDE just like it was done for the ESP8266, but not everything is working at the moment (see here). This add-on for the Arduino IDE allows you to program the ESP32 using the Arduino IDE and its programming language. If you like the ESP32, you might also enjoy reading all my ESP8266 […]
