How to Calibrate a Soil Moisture Sensor with Arduino?

Different kinds of soils affect the sensors differently, thereby leading to different readings. Therefore, it’s advised you use soil moisture sensors to suit the soil that’s being monitored. If you have a smart garden, then you’ll not only be able to measure the soil’s moisture but also know when to irrigate the plants automatically. The […]

How to Connect an LDR to Arduino

Light Dependent Resistor or LDR is also referred to as a Photoresistor. This simple device features an incredible characteristic whereby it changes its resistance in accordance with the light intensity, which hits it. When light is shone on it, the LDR’s resistance becomes lower; on the other hand, the resistance becomes more significant when the […]

How to Interface an Accelerometer with Arduino

There is no doubt that measuring acceleration is highly essential when it comes to carrying out several interesting projects. Usually, in an embedded system, this task is often carried out by an accelerometer. In addition to giving you the speed of an object, an accelerometer works as an indicator as well when a natural event […]

How to Fade an LED with Arduino

How to fade an LED with Arduino is one of the frequently asked questions. Therefore, in this article, we shall be discussing how to use an analog output PWM (Pulse Width Modulation) to fade LED using Arduino. The PWM technique is used in getting an analog-like behavior from any digital output. It achieves this by […]

How to Make a Syringe Pump with Arduino

You can build yourself a syringe pump and save yourself thousands of dollars. For as little as $200 and a less time, you can take it on as a DIY project. You get to control your fluids’ flow rate, depending on the projects you are working on. If, for example, you are working on 3D […]

How to Use 7 Segment Display on Arduino

A 7-segment display is an Arduino component for electronic display used to visualize decimal numerals, which are an alternative to the more complex presentations. It’s made up of seven LEDs (hence its name), which has a rectangular arrangement. Each of the seven indicators is referred to as a segment. This is due to its ability […]

How to Make Multiple LEDs Blink with Arduino

How to Make LEDs Blink in Multiple Ways with Arduino

So you want to learn about how to cycle through different LEDs on your Arduino natively? You have come to the right place. Unleashing the power of loops and the random function in Arduino’s IDE will allow you to light up any display. Think Christmas lights, art exhibitions, displays, and much more. We will show […]

How to Effectively Receive Arduino Sensor Data on an Android Smartphone

The Arduino is an excellent device but unfortunately it doesn’t feature an LCD display to help you see the sensor data. Therefore, in case you want to see temperature data or the pressure of your Sensor, you need something else to do that. If you have data that you want to see, it is recommended […]

How to Use a Timer in an Arduino Uno

In 2005, the Arduino Development Platform was originally launched as a user-friendly programmable device for art and design projects. The main objective of this launch was to help those without engineering skills to work with micro-controllers and basic electronics without the need of having so much programmable knowledge. However, due to its user-friendly capabilities, soon […]

How to Make a Bluetooth Car with Arduino

Have you ever been fascinated by a remote controlled car, or better yet, wondered how it was made? Well, such has been the case with many people who’ve grown around electronically controlled devices. The element of control has been with us since our childhood and most of us have fantasized about controlling cars, airplanes, ships, […]
