Home appliance control using Android phone
With increasing technology, Automation has become a need whether it is home, office or some other place. At home we come across many appliances be it Fan, AC, TV, Lights, etc. What if you could operate all of them with the Android Phone you’re holding in your Hand..!!This Project aims to incorporate android phone control over electrical appliances. We use Bluetooth communication between Android phone and a Receiver (control unit) that is connected to the appliances.
AC Power Controlling using Microcontroller through PC
As today world completely depends on the power saving, this prototype will help to decrease the power consumption. Here we are using this circuit for today’s world to control AC 60W bulb using 8-bit microcontroller and we are using the concept of pwm (pulse width modulation) technique to control the 60W load by which we can decrease the light intensity and thus power consumption of the load indirectly got decreased. The concept is very low such as to decrease the intensity we need to decrease the voltage of AC input. Here we are using a controlling part which consists of a TRIAC to control the AC voltage and also other feature is controlling the frequency of the signal. Keep on reading to find out how the circuit is assembled and put to use.
Remote control for AC Drive
AC Drive is widely used and probably a vital controlling device in the field of industrial automation. Most of manufacturing industries, continuous production units, chemical industries, textiles miles, pharmaceutical industries are now equipped with most advance industrial automation and to control various AC motors the ultimate solution is AC Drive. What’s an AC Drive? AC Drive is actually…
AC Voltmeter with Digital Display
In Electronic field voltmeters have found an essential place, Voltmeters are of two types AC &DC and here I have demonstrated a working AC Voltmeter. It has a large range from 0V to 1000V.The output is shown on 7 segment display.The main part of this project are :- Converting Circuit(For converting Ac to dc in range of 0-5V), ADC Interfacing(10 bit Inbuilt ADC of 16F676), 7 Segment Multiplexing.I have used PIC 16f676 microcontroller in this circuit. It has bridge rectifier which is made from diodes In4007.It convert Ac Voltage to Dc Voltage. Next is Voltage divider circuit which converts any voltage from 0 to 1000v to 0 to 5v range. It is made using two resistors and a potential meter in series. Next capacitor is used for removing ripples .the zener 5.1V is used for protection it will never give voltage to controller more than 5.1 V.
