using the /XOR/ gates, and LED indicators. Before assembling the circuit we need to know where the IC should be connected, therefore we first need to create the truth table and create a circuit diagram based on the results of the truth table. After completing the first and second process we need to determine the logic gates diagram of the IC being used in the circuit, and then we simply assemble the circuit by implementing the output based on the circuit diagram and connect the wires to their designated input and output points of every element in the circuit. A Seven Segment Display (SSD) is a form of electronic display device for displaying decimal numerals. This is widely used in digital clocks, electronic meters, and other electronic devices. In this activity, we will show how we were able to display decimal numerals (0-9) using binary coded decimal via the SSD. Before proceeding on, be sure to have an idea how an SSD work and mostimportantlyits pin configuration. Below is an image showing the pin configuration of the SSD. SSD has two types of common. The Cathode and the Anode. The cathode is a common ground while an anode is a common vcc. As for this experiment, we used a cathode, because its common is ground and all our inputs are positive, since an IC produces an output of apositivevalue. As you can see on the image, there are 7 inputs for this component device. By analyzing thiscomponent, we can use a 4bit binary...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
