Now connect a ohm resistor to the positive power rail and the other lead of resistor to the positive lead of led. A resistor is added here to prevent the led from burning as a 9v battery gives a higher current than the led requires. Connect a 9v battery to the power rails through a battery clip. Now switch the circuit on, this will make the circuit closed on and current will flow from positive to negative thus illuminating the led. After that switch it off, now the led will stop glowing as you have made the circuit open off.
As the circuit is broken, current will not flow thereby not illuminating it.
Step 2: Parts and Tools
Note: Use a 1K resistor instead of ohm for better results. Using a ohm can damage the resistor as well as the LED. Description: This is simple project that can be made easily in five minutes. It is a musical bell that produces a melodious sound just like doorbells. It uses the um66 ic popularly known as the melody ic which has a built in oscillator and an amplifier which can directly drive a buzzer but needs an external circuit to drive a speaker.
The supply voltage if the ic is 1. Instructions: Connect everything to the breadboard according to the layout given above. Refer to the images above for the pin configurations of the transistor as well as the ic. Do not connect a 9v battery as it would burn the ic. On switching it on, a musical sound will be heard.

Description: This is another simple project to learn about infrared light. It is an IR remote tester which can be used to test an IR remote whether it is working or not. IR remotes are basically TV or music player remotes.
The circuit makes use of an IR receiver which gives a repeated high and low output when it receives infrared light. TV remotes have an IR led in front of them which is use to transmit signals so if the led is working and the receiver is receiving, that means the remote is working. Since infrared light has a higher wavelength than our eyes can see so we are not able to see it however it can be seen clearly using a camera.
The circuit is so modified that if you press a button on the remote, an led will glow indicating that the remote is working. Instructions: Connect everything according to the layout given above. Refer to the image above for pin identification of the components. Connect a 9v battery to the power rails and switch it on.
Now bring an IR remote near it and press any button. The led would glow indicating that the remote is working. Giving it a higher voltage can damage it however it still works with it.

Also use a ohm instead of ohm connected to the LED for better results. The circuit is a little different but uses the same principle of the circuit mentioned above. Here is a step by step video for the same:. Description: You may have read that static electricity is the type of electricity in which the charges are at rest. It is present almost everywhere around us. So this is a project which can check the presence of static electricity around us.
If you touch it to anything, the led will glow indicating the presence of static electricity. The circuit is so sensitive that it can detect your hand even if keep it near to the antenna without touching it. Instructions: Connect everything as shown in the layout about. Look at the image above for the pinout of bc Extract a piece of wire from the base of the third transistor which will act as an antenna to detect charges.
After completing everything, switch it on and bring your hand close to the antenna. The led would glow dimly. Now touch your finger to the antenna. This time the led would glow brightly. Related project: Check out this Ridiculously Sensitive Electric Charge Detector that uses another circuit but does the same job.
Description: This project uses a timer ic which is the most commonly used timer ic by hobbyists. This project will produce a sound just like a ticking bomb as it is clear by the name. The timer is wired in astable multivibrator mode so produces a square wave output waveform which is nothing but switching the output between high and low. The circuit is set at a frequency of 1hz so it produces a tick every 1 second. The frequency of the circuit is determined by the value of the resistor and the capacitor present on the left hand side of the circuit. Another capacitor is added at pin 3 to stabilize the output to drive a speaker.
An led can be added in place of speaker by removing the capacitor at pin 3. Instructions: Connect all the parts on the breadboard as per the layout given above. Be careful when putting the ic on the breadboard and make sure that the small semi-circle present on the top of the ic should face left hand side when looking from the front. Do not alter the power supply which was made earlier in step 4. On switching it on, you would hear tick-tick sound coming from the speaker.
Related Project: Check out taipeihackerspace's Ticking Bomb Package that can be packed in a box and used as an april fool's day prank. Description: As the name already tells, this project fades an led high and low. This is done through the capacitor that is added on pin 3 which repeatedly charges and discharges producing a fading effect which is quite pleasing to see than to think. Instructions: Make all the connections looking at the layout above. On switching the circuit on, the led would fade off then fade on and will repeat until you switch it off. You can try different led colours to produce better effects.
Related Project: Check out soraj's USB Fading Star that uses the same circuit but the leds are wired in the form of a star that fades up and down. Description: As explained earlier, ldr is a device which gives a certain resistance depending upon the light falling on it. So this circuit makes use of and ldr to switch on an led when it receives a high amount of light falling on it.
An ldr gives a low resistance when receiving more light so the timer is triggered when light falls on the ldr and the output becomes high switching on the led. The output becomes low when no light is falling on it. Ldr has no polarity so connect it in either way. Now switch the circuit on, the led would glow if there is enough light in your surroundings.
Now enter a dark room, the led would go off. On putting a glowing torch just above the ldr, the led would glow again. Related Project: Check out C. Hariharan's Timer Based Light Seeking Robot that uses the light detector circuit to make a light following robot.
The circuit can also be used as a burglar alarm and a morning alarm. Description: This project has a reverse configuration of the previous project. It can detect the presence of darkness. The timer is triggered when ldr receives low light making the output high and switching on the led while when more light is detected, the output becomes low switching off the led. This type of circuit is used in automatic street lights that switch on automatically when it turns dark. Instructions: If you still have the previous project on your breadboard, do not alter the connections but just switch the connection of ldr i.
On switching the circuit on you will notice that the led will not glow initially. Now keep your hand above the ldr to block the light or enter a dark room. The led would glow this time as the ldr is not receiving light. Related Project: Check out ManishVarma's Automatic Streetlight System that uses the circuit to switch on a street light when it turns dark. Description: This is a project used to change the brightness of an led by varying the resistance using a potentiometer which has a knob that can be turned to set it at a particular value.
The circuit is somewhat similar to PWM pulse width modulation circuit which is used to control the speed of motors. The brightness is altered by switching the led between on and off at a fast rate which reduces the brightness. The rate is controlled by the potentiometer thus changing the brightness. Make sure you connect the diodes in the right way as they have polarity.
Switch the circuit on and turn the pot slowly. You will observe that the brightness of the led changes. Related Project: Check out my Desktop Lamp instructable that uses a similar circuit to change the brightness of 36 leds in a reading lamp. Description: Have you heard about electronic dice before?
