Hand Battery

                                                Hand Battery : Harnessing electricity 

Well !! You πŸ‘‰πŸ‘‰ are also a battery !! A human powered one !! πŸ˜€πŸ˜€πŸ˜€Lets check this out.

Item list 
  •  2 x cardboard covers
  •  Copper plate 
  •  Aluminium foil
  •  2 x jumper wires 
  •  A few paper clips 
  •  Multimeter 

Procedure.
  • Mount the copper plate on one of the cardboard covers and cover other cardboard cover with Aluminium foil. 
  • Connect the two above prepared  plates to the multimeter test probes using the jumper wires.
  • Set the multimeter to  the 200 milliampere setting. 
  • Place one hand on each plate and observe the readings. If negative current is shown in the.meter, then simply reverse the connections of  the multimeter probes.
  • You can even wet your hands with water (or sanitizer works the best) to make your hands more conducting and increase the multimeter reading!!!

Principle.
  • Sweat on your hands acts as an electrolyte. 
  • Copper gives up negative electrons when touched and becomes positively charged. 
  • When the aluminium plate is touched it takes negative electrons and becomes negatively charged.
  • The difference creates flow of electrical charges or current.
  • Electrons flow from plate πŸ‘‰ meter  πŸ‘‰ copper plate  πŸ‘‰body πŸ‘‰ forming a hand battery!!!

Measuring The Speed Of Light

Image
Have you ever wondered how fast does light travel ? We can measure the speed of light in our home using just our home appliances through a simple(and tasty !!) activity. Item List For this you will be needing: 1. A microwave  2. A bar of chocolate ( eggs work too!!) 3. A ruler  4. and a calculator. Principle A Microwave oven as the name suggests uses microwaves to heat our food. These microwaves are a part of the Electro-Magnetic spectrum and lie between Radio Waves and Infrared Waves.     The interesting part is that these micro waves travel at the same speed as that of light. Viola! Calculating the speed of these micro waves would give us the speed of light. Now thankfully we have a handy equation to calculate this :-        Speed of Microwaves (Light) = Wavelength (  Ξ»)   x  Frequency (  Ξ½ )          Experiment Frequency - You may find this at the back of your microwave (usually 2450 MHz) o...

 LCD KEYPAD DOOR LOCK USING AN ARDUINO   Hi ! how about locking your room using an LCD door lock. That would be nice, especially so if you want to lock out a pesky sibling. πŸ˜„ THIS IS WHAT YOU WOULD REQUIRE An Arduino Uno Micro Controller  16 x 4 LCD display  12 V DC solenoid door lock  Led Lights  Some jumper wires for the connections    9 V battery (an external power supply more closer to 12 V  would be better ) Relay  10k potentiometer 220 Ohm resistor 4 x 4 keypad  HOW DOES THIS DOOR LOCK WORK   πŸ”πŸ”πŸ” When one enters the password for the door lock, the keys pressed match with the  default keys.  The solenoid lock is activated and the door lock opens.  Simultaneously, the LCD also displays a 'Welcome' message.   If the keys do not match the default password then the door lock remains closed. The LCD also displays 'Wrong Password' CIRCUIT DIAGRAM THE CODE  After setting up the circuit as shown a...

ARDUINO OBSTACLE AVOIDING CAR - A TUTORIAL GUIDE

Image
I wanted to work on building a robotic car that could maneuver on its own and avoid obstacles.  This project was an extension to the ' Smartphone Controlled RC Car ' project I worked on last year during the pandemic. You can read   more about that project here . ARDUINO OBSTACLE AVOIDING CAR - A TUTORIAL GUIDE Components Used Arduino Uno L298N motor driver HC-SR04  distance sensor Servo Motor Cardboard and wheels for mounting everything Description For the project I attached the HC-SR04  distance sensor on top of a servo motor. The servo motor would rotate the distance sensor which could then scan the room and send data to the Arduino microcontroller. If  the sensor detected an obstacle within its proximity, the Arduino would then via the L298N - motor driver change the  RPM of either of the car's tires - effectively changing the direction.   Here is the video I made detailing every step through the entire build of the project. :)

MORSE CODE - HARNESSING ELECTRICITY TO COMMUNICATE

Image
   HARNESSING ELECTRICITY TO COMMUNICATE - MORSE CODE Morse code  is based on name of its inventor Samuel Morse and was used first in 1844. For well over 100 years it was extensively used for communication including during the World War 1 and World War 2. UNDERSTANDING MORSE CODE Here is a video to understand the Morse Code and you can also try a few android apps to get the hang of Morse Code STARTING THE PROJECT An excellent resource to understand the Morse Code  and execute this project of harnessing electricity to communicate is via the Microsoft Education Workshop site     https://www.microsoft.com/en-us/education/education-workshop/telegraph.aspx Collecting materials for the project was super cool. It's mostly available online via Amazon or other web portals. A simple Google search and would suffice. I used an Arduino Uno micro controller for the project but you can use a Microbit micro controller also. PROCESS Lets get started.....first...
