555 Timer IC Tester

Engineeering Projects
circuit diagram of 555 ic tester

NE555 Timer IC  is very popular and one of the most commonly used components in electronics circuits. NE555 Timer IC is also called Ideal IC since it offers multiple features like multipurpose functionality, low power consumption, small size, and durability. When we work on a particular project and it doesn’t work the way we wanted, before the circuit we doubt whether the IC used, is working or not. More or less, blaming IC is reasonable since IC is the combination of many more components or IC itself is a combination…

Dry Cell Charger | Easy Electronic Projects

Engineeering Projects
circuit diagram of dry charger

We all are fed with the fact that dry cell is not rechargeable and it has no use once it is discharged during use. And, people simply throw it away and buy a new one. Because of this, people are forced to invest quite a lot on battery. In order to overcome this problem, here we have presented a new project ‘Dry Cell Charger’, which has been tested and verified practically. Using the circuit dry cell charger one can charge dry cell 6 to 8 times which evidently contributes to…

Woofer Tweeter Crossover

Engineeering Projects
circuit diagram of woofer tweeter crossover

When using speakers, people must have faced quite a lot of problems due to failure of the speaker to produce smooth sound quality continuously. It is because speaker detects only identical frequency and does not give response to all frequency.  Particular range of low frequencies is detected by the speaker and it ignores high frequencies. Woofer or tweeter is introduced as a solution to this issue. However, if the signal from amplifier is directly fed to woofer or tweeter, then it may not produce the actual sound. And, a crossover…

Capacitor Tester cum Flasher

Engineeering Projects
capacitor tester circuit diagram

Capacitors are one of the basic components of any electronic project. Now, here we taught you, how to test capacitor whether is short, open or working. The simple circuit of the capacitor tester is built around two general-purpose NPN transistors. This circuit posted here is used to test capacitors up to 1000 µF. The capacitor to be tested is connected at points A and B as shown in the circuit diagram (positive terminal at point B where negative terminal at point A). Working of the circuit Capacitor Tester cum Flasher When…

High Powered Strobe Light Using Arduino

Engineeering Projects
arduino based high powered strobe led light

The project High Powered Strobe Light Using Arduino is the extended version of strobe light using arduino. Here, in this project we uses six high power Luxeon LED as used in previous project. This project show different strobe effect like flashing, fading, continuous illuminating etc. We can select any of this effect through serial monitor. Lets see the circuit diagram and how its work. Circuit Description of High Powered Strobe Light Using Arduino The circuit is shown in figure 1 and is designed around arduino uno board, N-Channel MOSFET, LM317…

circuit diagram of led strobe light using arduino

Here is one another project which is useful in our daily life using aduino. As we had already posted “High Brightness LED Strobe Using NE555” using array of 36 LEDs now here we use single high brightness Luxeon LED. The circuit of strobe light using arduino is shown in figure 1. The potentiometer VR1 is used to control the flashing rate of strobe light. PARTS LIST OF STROBE LIGHT USING ARDUINO Resistor (all ¼-watt, ± 5% Carbon) R1 = 270 Ω R1 = 4 Ω/1W VR1 = 100 KΩ Semiconductors…

circuit diagram of sound VU meter using arduino

Different gadgets have been introduced to meet our requirements ranging from the basic needs to the classy needs of humans. With this development in recent years, people have grown more sophisticated day by day. Hereby we have presented a circuit sound VU meter using Arduino to display the volume of noise picked up by a microphone. Circuit Description of Sound VU Meter using Arduino The push-to-on switch SW1 is used to change the mode of the sound VU meter. In normal mode, the LEDs just flicker up and down with…

LED Dice Using Arduino

Engineeering Projects
circuit diagram of ed dice using arduino

Here you will find the tutorial to build a simple LED dice using arduino. The software build will be reliable and perfect enough to implement it in a real working environment. This project is very helpful in to build a basic arduino system. Arduino technology is easy to use, efficient and reliable where it also allows dynamic and faster control. In this project we used random number generation technique. Every time you press the button, the LED’s roll for a while and glow a single LED. Figure 1 show the…

Dynamic Temperature Indicator and Controller Using Ardunio

Engineeering Projects
circuit diagram of dynamic temperature indicator and controller

Here is a standalone Dynamic Temperature Indicator and Controller Using Ardunio that also controls the electric appliance according to temperature. The use of Arduino technology makes this closed-loop feedback control system efficient and reliable. Arduino allows dynamic and faster control. Here we used a rotary encoder and liquid crystal display for more users friendly. The sensed and set temperature values are simultaneously displayed on the LCD panel in centigrade which can be changed Kelvin in scale. Circuit Description of Dynamic Temperature Indicator and Controller Using Arduino The circuit is programmed…
