    my previous project was a dark detector (which glow LED in dark)
    now i want to make something else
    i have a small bread board & some resistors ,let , LDR & some basics thing

    is there is any thing i can make on breadboard ?



    thxx in advance
    PS i dont have solder & down want to work with PCB & soldering
    just want to make some simple things for fun & learning

    With only those components what about an LED that turns on in the light and off in the dark. What are the other basic things? Do you have any transistors?

    i already make an dark detector

    & ya i have some transsistors
    like BC547 & some IC
    dont worry these things are rally cheap
    so i can buy them
    but i dont want to buy any expensive thing

    i can also but some motors , microphone etc..

    Get a few capacitors low value ceramics and a few electrolytics.

    Transistors will be a very good friend while you learn.
    They can be used to build anything from a small audio amplifier to a set of complex logic gates.

    They can be turned 'on', 'off', or anywhere 'inbetween'. Your LDR project was built to allow the LDR to control the transistor to turn it on/off which allows the transistor to complete a current path for the LED.

    What about an LED flasher circuit?

    You can make that with transistors, resistors and capacitors! :)

    Edit: And an LED of course ;)

    lol :p
    i google it & its was like a disco light (low light then high light then again low)
    but dont understand for what purpose it can be used

    & whats 555 ???

    Well. You are constructing a very basic oscillator, which has a wide variety of uses. More complex circuits use a different type of oscillator though.
    A 555 is an IC commonly used for application requiring some sort of timing. They are commonly used in applications that require delays, clock pulses or some other form of time tracking.

    Then build a robot ;)

    You will need a robot idea that you can build in your time-frame.
    You are restricted by the parts you require and your current working knowledge.

    If you want to go wireless, throw away the idea unless you can order and receive a wireless transmitter/receiver pair. Don't bother making something wireless without it.
    If you want to be tethered to your robot, you just need some push buttons, and (optionally) transistors to control the motors.
    If you want an automated robot, you will need transistors, a basic knowledge of how to turn them on and off. You will also need sensors, or components that offer you timing. (An LDR is a sensor)

    You also need to mechanically build it and pick motors, or servos that can handle what you want.
