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 …
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 …
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 …
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 …
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 …
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 …
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 …
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 …
Digital code locks are most common in security systems. An electronic lock or digital lock is a device which has an electronic control assembly attached to it. They are provided …
