“Sadly, in the name of progress, we have polluted the air, water, soil and the food we eat”. So monitoring the air quality is very crucial now days because of pollution. For designing an air quality monitoring system we need durable and reliable air quality sensor. Although there are many Air Quality parameters but the most important are CO2 and TVOC. So for sensing CO2 and…
In this tutorial we are introducing concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. Arduino board has six ADC channels, as show in figure below. Among those any one or all of them can be used as inputs for analog voltage. The Arduino Uno ADC is of 10 bit resolution (so the integer values from (0-(2^10) 1023)). This means that it will map input voltages…
Frequency is defined as number of cycles per second. It can also be defined as reciprocal of total time ‘T’. In this project we are going to count the number of pulses entering into Port 3.5 of 8051 microcontroller and display it on 16*2 LCD display. So basically we have measuring the frequency of signal at Port 3.5 of 8051. Here we have used AT89S52 8051 chip, and a…
VU Meter or Volume Meter is very popular and fun project in Electronics. We can consider the Volume Meter as an Equalizer, which is present in the Music systems. In which we can see the dancing of LEDs according to the music, if music is loud then equalizer go to its peak and more LEDs will glow, and if music is low then lesser number of LEDs shall…
Radio Frequency Identification (RFID) uses radio frequency to read information stored in a RFID card or tag. In this project we are going to Interface EM-18 RFID reader with 8051 microcontroller and display RFID card number on 16*2 LCD display. This wireless RF Identification is used in many systems like RFID Based Attendance System, security systems, voting machines etc.…
In this tutorial we are going to interface a joystick module with atmega8 microcontroller. A JOY STICK is an input module used for communication. It basically makes easy the user machine communication. A joystick is shown in below figure.
The joystick module has two axis - one is horizontal and other is…
In a general way, the Cable Tester is the device by which we can check whether the cable has defected or it is connected in a proper way. A cable tester is the very useful way to determine the physical quality or connectivity of the cable or wires individually while installing them. It detects whether the cable is connected properly and the communicative strength between the…
One of the most commonly used sensors in Electronics is IR sensor (Infrared Sensor). IR sensor helps in detecting the heat and the motion of an object. In the infrared spectrum, all the objects emit some form of thermal radiations. These radiations are invisible to a human eye and can only be sensed or detected by an IR sensor. An IR sensor consists of IR Transmitter which…
Infrared sensors are much common in our electronics life. They are used in many real time applications like for opening and closing the gates at Metro Station. Even they are used in our Mobile phone to turn off the display light during the call.
IR sensor is very popular sensor, which is frequently used in many applications in electronics, like it…
In this project, we are going to make a Voice Modulator Circuit, by using self-designed PCB. In this project, we have designed a PCB using EASYEDA online PCB simulator and designer. This is a fun project, mainly designed for changing or altering the voice. Generally, when we speak in a MIC we hear same voice. But in this project when we speak in MIC, we will hear a little…
Multi-way switching is the most common method to be found in the electrical system. It provides user the comfort to turn ON and OFF any electrical appliances from more than one place. The most common use of multi-way switching is for lighting systems and placed in the most common areas of a building like hallways, reception area, kitchen, living room and many other. Multiway…
Voltage Tripler is the circuit where we get the thrice of the peak input voltage, like if the peak voltage of AC voltage is 5 volt, we will get 15 volt DC at the output. Generally transformers are there to step-up or step-down the voltage, but sometimes transformers are not feasible because of their size and cost. This kind of voltage tripler (voltage multiplier) can be…
