How To Post On Twitter From Arduino and ESP8266 IoT Project

Twitter is a free social platform that can be very useful for your IoT project. You can use it instead of paying for a messaging platform. In this project, I will teach you how to use Twitter to send temperature alerts from your IoT project. The project utilizes ESP8266 WiFi module to connect Arduino to the internet. The WiFi module connects to your home WiFi for the internet. You can also use the ESP8266 alone but in this simple project, we shall use it together with Arduino Uno. For integration with Twitter, we use Thingspeak’s ThingTweet App. We connect to […]


How to Control a DC Motor with H-Bridge and Arduino and IR sensor

A motor is a device that converts electrical energy into mechanical energy. It is arguably the most important component in a robot because it is responsible for all the structural movements. In robotics, DC motor, stepper motor, and servo motor are the three common types of motors. Each is ideal for a particular application. In this project, the focus will be on the use and control of a DC motor. A DC motor is the simplest of the three aforementioned types of motors. It consists of two terminals. These terminals must be connected to a DC source such as a […]


How To Use a 4-Digit 7-Segment Display in Arduino Project

A seven-segment display is one of the simplest and cheapest electronic display units. It is used to display numerical output that has few place values or decimal places. 7-segment indicators exist in different forms. Some of the common types are one-digit, 2-digits, 3-digits, and 4-digits display units. Of those that have more than one place value, there are those that have decimal points and colons. The seven-segment display units with decimal points are ideal for displaying numerical output with few decimal places while those that have colons are mostly used to display time. Though simple in design, a 7-segment display […]


How to Use a TV Remote as Input Device in Your Arduino DIY Project (Video)

When you want to incorporate short-range wireless communication in a project, infrared signal is one of the protocols you can consider. Infrared communication is the use of a modulated low-frequency light signal that can be used for short-range wireless communication between devices. It is the technology used by TV remote controls to operate a Tv remotely. There are multiple other devices that utilize the infrared remote controls as input devices. Similarly, you can use an existing IR remote control as input in your project. All you need is a simple IR sensor circuit and a microcontroller. The IR sensor circuit […]


How to Control Digital Output with Digital Input on Arduino Board

One of the first things to learn when beginning to build projects with various development boards is how to control simple outputs with simple inputs. Accordingly, the digital inputs and outputs are considered the easiest to start with because there is not much to worry about except the zeros and ones or rather the binaries. In contrast, analog I/Os require you to worry about the continuous variable states of data. In this simple arduino beginner project, you will learn how to control LEDs (as digital outputs) with a push button (digital input). In addition, you will also learn how to […]


VIDEO: Resolving Issues Arising from Launching ESP8266 into AT Mode Using Arduino’s 3.3V [VIDEO]

They say a picture is worth a thousand words and I think a motion picture is worth two thousand. Watching a video demo clears the confusion that may result from learning by reading. I happen to be one of those guys who prefer learning by watching especially after studying the theories around something. After writing the article: How to Launch Your ESP8266 WiFi Module into AT-MODE Using Arduino Uno, I found it fit to follow it up with a video demo. The demo specifically demonstrates: How to connect the ESP8266 WiFi Module directly to the Arduino’s 3.3V pin How to launch the […]
