Analog Electronics deals with electronic systems that has a continuous variable signal. In this section we will discuss about various analog electronic projects that can be used to design your own amplifiers, oscillators, filters, analog converters, waveform generators and other analog circuits as required by your application.
In our daily life we see vehicles turning indicators when they turn left or right. It looks like Simple LED Blinking. But it's not only simple blinking LEDs inside indicators of vehicles. Here we are building a fancy Car/Bike Turning Indicator Circuit using 555 Timer IC, with four LEDs glowing one by one in a particular pattern and we can control the speed or frequency of…
In this project let us develop an LED Strobe light circuit using the popular 555 timer IC. A strobe light or a stroboscopic lamp is one which can produce regular flashes of light. We are designing this circuit using a 555 timer for setting the delay between each flash and a high power LED light as the source of light. At the end of this project we will learn how to use 555…
In this project we are going to build a Digital Voltmeter without using any microcontroller. Here we are using a very popular IC for voltage measurement namely ICL7107/CS7107. Using ICL7107, we can build accurate and very low cost voltmeter. ICL7107 is a 3.5 digit analog to digital converter (ADC) which consumes very low power. The IC has internal circuit for driving…
We have previously built 3x3x3 LED Cube using Arduino and Raspberry Pi. 3x3x3 LED Cube is generally build using some microcontroller, but in this session we are going to make a 3*3*3 LED CUBE without any microcontroller. Here we will use 555 timer IC and CD4020 binary counter setup to control the LED Cube.
Normally for controlling an LED CUBE, we…
Previously we have built Temperature controlled LEDs Circuit, in which two LEDs were glowing according to the temperature. Now we are enhancing that circuit by using a Relay, and now we are going to Control Home AC appliances according to Temperature. This circuit will serve as automatic light switch which will trigger if temperature goes beyond a particular level (50 Degree…
Digital Code Locks are very popular in Electronics, where you need to enter a particular ‘Code’ to open the Lock. This type of Locks needs a Microcontroller to compare the entered code with the predefined code to open the Lock. We have already built these kinds of Digital Locks using Arduino, using Raspberry Pi and using 8051 microcontroller. But today here we are building…
Today we are building a simple yet very useful circuit using Temperature Sensor LM35. In this circuit, we are going to control the LEDs according to temperature around. If temperature goes beyond a particular level (50 Degree in this circuit) then Red LED will glow automatically, otherwise yellow LED remains on below that particular temperature. This threshold temperature…
You have seen Automatic Wiper System in luxury cars where Windshield Wiper automatically gets activated when there is Rain or if there is some water on the windshield. Electronic Wiper is very common device that is attached in every car to wipe the water on the windshield during the rain. But generally they are manually operated and we need to switch them ON manually. But…
Infrared sensors are much common in our electronics life. They are used in many real time applications like for opening and closing the gates at Metro Station. Even they are used in our Mobile phone to turn off the display light during the call.
IR sensor is very popular sensor, which is frequently used in many applications in electronics, like it…
Almost every electronic hobbyist must have faced a scenario where he or she must measure the frequency of a signal generated by a clock or a counter, or a timer. We can use an oscilloscope to do the job, but not all of us can afford an oscilloscope. We can buy equipment for measuring the frequency, but all these devices are costly and are not for everyone. With that in…
Transistors are the semiconductor devices used for switching or amplifying electrical signals. They are highly durable, smaller in size and operates on a low voltage supply. A Transistor is a three terminal device:
Base: This pin used for activating the transistor (minimum 0.7V required to turn ON a Transistor) Collector: Current flow through…
Transistors are made up of semiconductor material which is most commonly used for amplification or switching purpose, although they can also be used for controlling the flow of voltage and current. Not all but most of the electronic devices contain one or more types of transistors. Some of the transistors placed individually or else generally in integrated circuits…
