It’s all started with a small game from the dark ages called “Mario”, right from the time of being a tiny little guy jumping on ducks to save my princess till being a masculine handsome Prince roaming in Persia (Prince of Persia) fighting against darkness to save my world behind I have been a great fan of playing video games and I grew up playing them. But they do get bored…
The Iconic name “Nokia 5110” itself should have bought memories of the robust Nokia mobile phone which was very popular during the 90’s. The model 5110 came with a Graphical Display which was sufficient enough to act as a display screen for the mobile back then. This screen was capable of displaying everything from alphanumeric characters to small graphics that is everything…
Batteries come with a certain voltage limit and if the voltage goes beyond the prescribed limits while charging or discharging, the life of the battery get affected or reduced. Whenever we use a battery powered project, sometimes we need to check the battery voltage level, whether it is needed to be charged or replaced. This circuit will help you to monitor the voltage of…
“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…
In this project we are going to make Clapper circuit using the concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. We are going to use a MIC and Uno to sense the sound and trigger a response. This Clap ON Clap OFF switch basically turns ON or OFF the device, by using the clap sound, as switch. We have previously built Clap switch and Clap ON Clap OFF…
Humidity and temperature are common parameters to measure environmental conditions. In this Arduino based project we are going to measure ambient temperature and humidity and display it on a 16x2 LCD screen. A combined temperature and himidity sensor DHT11 is used with Arduino uno to develop this Celsius scale thermometer and percentage scale humidity measurement project. In…
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…
