Robotics Session-Day 2

This is what the students have learnt on day 3 of the camp and day 2 of robotics session 

Some symbols:

TYPES OF CIRCUITS:

 

Advantages of parallel combination over series combination are: (i) In parallel combination each appliance gets the full voltage. (ii) If one appliance is switched on, others are not affected.

Disadvantages of series circuits: (i)An open in any one device will also interrupt current flow to all remaining devices.(ii)A short in one device will cause an increase in current through all the devices.(iii)Changing the resistance value of one device will change the current, voltage, and power values of all remaining devices.

RGB is an LED chip that has the color red, green and blue; 3 colours in 1 chip. Using these, you can create a million different colours.

RGB LED controllers work on a much simpler principal. They change the power on each of the three channels (red, green and blue) to produce a specific colour mix. To create purple colour, for instance, the red and blue channels would be wound up, and the green channel should turn off completely.

There are four terminals in RGB,1 cathode(negative) and rest 3 anode(positive).

Resistors can be used to change or control power supply.

Breadboard

A breadboard is a simple device designed to let you create circuits without the need for soldering.

Many electronic devices is used to connect and positive terminate of battery is connected to positive terminal of breadboard and negative to negative.

 

ARDUINO UNO

                          

ADRUINO HAS COMPONENTS LIKE:

·       DIGITAL PINS-WHERE POSITIVE TERMINALS OF ELECTRONIC DEVICES ARE CONNECTED.(0-13)

·       GROUND PINS-WHERE NEGATIVE TERMINALS OF ELECTRONIC DEVICES ARE CONNECTED.

·       POWER PINS- TO SUPPLY POWER

*ARDUINO UNO CAN ONLY HOLD MAXIMUM OF 5V POWER SUPPLY

·       ANALOG PINS- TO INSERT SENSORS LIKE SOIL MOISTURE SENSOR, PIR SENSOR,TEMPERATURE SENSOR,SMOKE SENSOR,ETC

          PROGRAMMING WITH ARDUINO

A software can be used to visualise or practice like Tinkercad

·       CLICK ON OPTION CODE AFTER PERFORMING A CIRCUIT.

·       THE FORMAT OF PROGRAMMING CAN BE CHANGED IN THE EDIT MODE BY BLOCKS OR TEXT.

·       IN THE OPTION OUTPUT, ENTER THE DIGITAL PIN NUMBER WHERE THE ELECTRONIC DEVICE TERMINALS ARE INSERTED.

·       WE CAN SET TIME INTERVAL OR THE ORDER EHERE ELECTRONIC APPLIANCES WILL BE ON OR WORKING.

·       MAINLY THIS PROGRAMMING IS USED FOR LED LIGHTS. 

PRACTICALLY CIRCUITS CAN BE PERFORMED WITH MOTOR,BATTERY,WIRESBREADBOARD,SENSORS ,ETC.
