Arduino Based multiple Device Control using Interrupt

device-control-using-interupt

In the project “Arduino Based multiple Device Control using Interrupt” you will learn how to control multiple appliance with two switches by using the concept of interrupt. In this prototype we are going to control four devices using two interrupt pin (switch). You can increase or decrease the number of devices according to your requirement but number of switches is same (two). When button is pressed, interrupt sun-routine is called and control algorithm runs. Features of Arduino Based multiple Device Control using Interrupt: Only two button switches are used to…

Three Phase AC Voltage Measurement using Arduino

Three Phase AC Voltage Measurement using Arduino prototype

Today, in this article, you will learn how to make Three Phase AC Voltage Measurements using Arduino. At first, we will show you how to measure single-phase AC voltage and then measure three-phase AC voltage. Features of Three Phase AC Voltage Measurement using Arduino: Can measure AC voltage of any amplitude. Show individual phase voltage. LED indication for individual phase voltage. For the protection of the control board (Arduino Board), a variable resistor is used i.e. output voltage must not be more than 4.5V even when Zener diode burnout. Working…

Interfacing Optocoupler with Arduino

Interfacing Optocoupler with Arduino

Today in this tutorial we will see the interfacing optocoupler with Arduino (4N35 or MCT2E). Optocoupler is also called an optoisolator. But before that let’s see what an optoisolator or optocoupler is? What is Optocoupler or Opto-Isolator: Optocouplers or optical isolators are designed to electrically isolate one circuit from another while allowing one circuit to control the other. The usual purpose of isolation is to protect from high-voltage transient, surge voltages, and low-level electrical noise that could result in an erroneous output or damage to the device. Such isolators allow…

Measuring Temperature using PT100 and Arduino

author prototype of Measuring Temperature using PT100 and Arduino

In this article, you will learn how to Measuring Temperature using PT100 and Arduino. PT100 is a platinum resistance thermometer, which changes its internal resistance according to temperature. In the name PT100, 100 represents ohm i.e. it offers 100-ohm at 00C. Similarly, PT1000 offers 1000-ohms at 00C. PT100 is widely used in industries because of its temperature range. From the nature of the resistance thermometer, we conclude that tolerance depends upon the range we are using it. When we used to measure temperature nearer to 00C (in both positive and…

Bluetooth Controlled Robot using Arduino

Bluetooth Controlled Robot using Arduino author prototype

This article shows you how to design a high-power motor driver for Bluetooth Controlled Robot using Arduino and relay. Previously, we had posted an Arduino-based Bluetooth-controlled car designed around L293D motor driver IC. There is some limitation of the L293D motor driver IC i.e. output current is limited to 600mA. What if you wish to drive a DC motor that consumes more than 1A? Let’s say 5A. For this, you need a more powerful circuit that delivers appropriate power to the motor. So, here you will learn how to make…

Pause and Resume Arduino Program using Switch

Pause and Resume Arduino Program using Switch author prototype

Arduino is an open source and become famous in very short time, due to its powerful features and simplicity. Arduino comes as boon for inventor, artist etc. One can make their own system without having much knowledge about core electronics and assembly programming. In this article you will learn how to pause the code and resume using a push button switch. Sometime, we want our code to run only when user do some action like to press switch of get some value of sensor. Few years back while making game…

Arduino Based Caller ID for Bike

author prototype of Arduino Based Caller ID for Bike

This article shows you how to make caller ID for two wheeler’s i.e. bike or scooter. This caller ID display cell phone number when any one call you or when you call anyone while riding bike or scooter. Sometime It is difficult to identify the caller while riding two-wheeler vehicles because usually we keep our mobile either in pocket or in bag. Sometime even we get confused whether the vibration is of vehicle or of mobile. By using this simple device one can know about caller and can easily distinguished…
