Circuits without coding

To start with circuits, we understood  the basic sign and symbols and were ready to start with the circuits.

First was as simple as just connecting the power source with one of the LED.

For which we used our coin battery of 3 volts with LED

Next was making the same circuit on bread board using burg wires (male to male), because the previous was very unstable.

Next  was using a switch in the same circuit and control the flow of current when pushed the button.

Next was using 450ohm and 10kilo ohm resistor to see the difference in LED intensity due to resistors and decreasing current flow.

Now we changed the output device in first circuit, which was LED with a buzzer.

Next was learning series and parallel connection on bread board.

SWITCHES  :-

Force Sensor – Force sensor is a variable resistance and can also work as switch.The force changes the value of resistance and in case of switch can close a circuit when force applied and also records the value of pressure applied accordingly.

Tilt Sensor or switch -  as explained in kit was used as it does not need any coding , the output device reacts according to the state of circuit. If circuit is on / close the device will give output either it will be switched off.

Tilt sensors are used in cars  and to detct the changes in axes.

Reed Switch  - Reed switch is made of two flaps of a material which gets influenced by magnetic field and such witch can be used to close a circuit in magnetic field and remain open in absence of magnetic field.

This switch can be used for hands free switch. and can be used in products for magic tricks.

Flex  Sensor – Flex sensor is a sensor which measures the amount of  flex or bending force applied on the sensor, and it does not need any coding but the burg wires are connected to aurdino  uno to get the values on device.

Used in door sensors.

Water sensor – It has tracks of circuits on it, and as one can figure out the process for what it is used is detection of water.

It can be used for detecting humidity (if made more accurate) and rain.
