Since electronics were created, electronic projects have become one of the most popular hobbies that existed. While the tools and components have become so advanced these days, the enthusiasm and fascination for the hobby itself remain true as ever. With …
There are several types of flow meters in the market these days. Most of them use complicated technologies to measure the volumetric flow, linear, nonlinear, and the mass flow rate of a fluid flowing through a pipeline. Fluids come with …
The open-loop control system and closed-loop control system are the two types of control systems that you will learn in this article with the help of 4 practical examples from your daily life. Before going to the details, you must …
In recent years, cells and batteries—especially cells—have become available in many different sizes and shapes besides the old cylindrical cells, transistor batteries and lantern batteries. In this article, you will learn about three types of miniature cells and batteries. Silver …
Using a resistor to limit the current can be used for small LEDs. For such low power LEDs, where the supply current is not critical it works okay. But for high-power Light Emitting Diodes, a better way is to use …
In this project, we will make an automatic irrigation system using Arduino microcontroller. Automatic Irrigation system monitors the soil moisture and depending on set points turns on/off the pump which is connected to the relay. This way you can keep …
A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display …
A servomotor is also defined as a rotary actuator that allows for very fine control of angular positions. This article explains controlling a servo motor with Arduino in detail. Many servos are widely available and quite cheap. Servos can drive …
The automatic light controller offers energy saving and convenience in the areas with a photosensor (LDR). LDR senses the ambient light conditions in the surrounding area and switches ON-OFF the lighting load. The darkness level in the surrounding is settable. …
