 1.    Dark sensor:

Description: As you block light falling on the LDR, the LED D1 switches ON. As soon as you put lights on the LDR, the LED goes off.

Extra experiment: The sensitivity of the circuit depends upon the value of resistor R3. If you replace the resistor R3 (4.7K) with some other resistor, for example 330 Ohm, it becomes highly sensitive to darkness and if you increase the resistance beyond 4.7K, it gets less sensitive to darkness. You can try it.

2. Latch Circuit

Description: When you press the tactile switch, the LED D2 switches on and when you press it again, the LED switches OFF. This is bistable mode of NE555 timer.

See how to make this circuit on breadboard.

Extra experiment:  You can do a simple experiment with relay also. You can make a light operated switch with this circuit.

The schematic for the circuit is given below:

In this experiment, when you press light falling on the LDR, the relay gets activated and switches on the LED2. Here, relay operates exactly like the tactile (momentary) switch.

3.    Astable Mode:

Description: In this experiment, the LED3 blinks according to the values of R3, R1 and C2. It has been configured in the astable mode of 555 timer.

Extra experiment:

 You can make an Infrared transmitter with this kit by just changing the values of resistors.

Schematic for IR transmitter is given below:

4.  Clap switch

Description: When you clap close to the electret microphone, it switches the LED4 ON for a while and switches off again.

When you clap, the circuit triggers pin 2 of NE555 timer and takes it to monostable mode.

The ON time is determined by the values of resistor R2 and capacitor C1. The timing is 1.1xR2xC1.

You can alter the timing of the circuit by changing the values of resistor R5 and capacitor C1. You can try with 100K and 100uF.

    LED Chaser Using NE555, CD4017, Infrared Receiver And Photoresistor

    The kit does work normally like a normal LED chaser kit. In addition to its obvious features, it has a photoresistor that allows you to change the speed of the chasing LEDs. In the old LED chaser, the speed is controlled with a variable resistor. In this kit, we have used a photoresistor to work as a variable resistor. As the light falling on the photoresistor changes, the speed of the LEDs also changes.

    This is 3 digits digital object counter kit for electronics beginners and hobbyists. It is the upgraded version of our previous 2 digits and 3 digits object counter.

    You can use this 3 digits digital object counter for counting objects or people entering in a room. It can be used by engineers for learning about digital counters.

    This DIY digital object counter works with VS1838 infrared receiver and photoresistor and there are three seven segment displays displaying numbers from 0 to 999. An IR transmitter is directed towards the VS1838 infrared receiver of the counter module and objects are moved between the two modules. Each time an object passes between the two modules, the seven-segment displays show increment in numbers from 0 to 999.
