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 soil moisture to a set point. This system automatically waters the plants when we are on vacation. As we are setting the soil … [Read more...] about Automatic Irrigation System Using Arduino
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 of voltage by use of an analog to digital converter. We are using internal ADC of Arduino to make Digital Voltmeter … [Read more...] about Arduino DC Digital Voltmeter
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 a great amount of current. This means that you wouldn't be able to use more than one or two on your Arduino board without using an … [Read more...] about Controlling a Servo Motor with Arduino
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. It is in-built with an additional PIR Sensor which TURNS ON Light in the presence of human and switches OFF after 10 … [Read more...] about Arduino based Automatic Light Controller
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 with an access control system. This system allows the user to unlock the device with a password. The password is entered by making use of a keypad. The user can also set his password to ensure better … [Read more...] about How to Make a Digital Lock Using Arduino?
