The important parts required for this project are : ARDUINO UNO 3 LEDs (red, yellow, green) Let us have some discussion over the above components. ARDUINO UNO This is the brain of …
We believe that the history of telecommunication began with the use of smoke signals. It is natural to assume it this way. It wasn’t until the early of the 1830s that electrical systems emerged. By then mankind was aware of the power in atoms and its electrons. This flow of electrons was termed Electricity. Soon …

Components required NPN Transistors Battery (9V) Resistors (1KΩ) Capacitor (1μf) Switch LED (Green) Diode Circuit diagram Working Here two NPN transistors are used as switches. When the probes …
This project presents an Smart Room Temperature system capable to autonomously control the temperature level by exploiting data related to temperature in that specific area. The system is able to set the temperature level on the basis of required needs and allows one to remain in constant temperature. To this end, it makes use of …
Introduction During these hard times like the COVID 19, it would be suitable to use an automatic dispenser. This helps one to use hand sanitizer without any touch thus eliminating the passage of virus through non-living materials. The automatic dispenser senses the presence of hand using sensors and sent a signal to drop the sanitizer …

INTRODUCTION This DIY project is also famous with the name of Liter of Light. Liter of Light is the open-source design for a low-cost light tube that refracts solar light to provide daytime interior lighting for those houses which have thin roofs. Using Daylight is cheaper than using an indoor electric light during day time. …
INTRODUCTION:-This a very interesting project in which we are going to tell how can an arduino can check wheather a person is lieing or not.In this project we will connect our arduino nano digital pins with the leds(number of leds can be vary as per the requirement of the individual ) .We get our required …
IR Based Object Counter is an Infrared object counter build using Arduino. IR LED emits infrared light, means it emits light in the range of Infrared frequency. We cannot see Infrared light through our eyes, they are invisible to human eyes. The wavelength of Infrared (700nm – 1mm) is beyond the normal visible light. We …
INTRODUCTION A Geiger counter is an instrument used for detecting and measuring ionizing radiation. Also known as a Geiger–Muller counter (or Geiger–Müller counter), it is widely used in applications such as radiation dosimetry, radiological protection, experimental physics, and the nuclear industry. Today, we will make a mini Geiger counter using Geiger counter module, Arduuino and I2C 16*2 LCD Screen where we will …
