Understanding Power Supply- Linear and Switch Mode Power Supply In need for power supply in your upcoming project? Confused between Linear and Switch Mode Power supply? or just want to understand how they work? Let’s try to find some answers. Contents of this post: Introduction Choosing Right Supply for your Project Design PART 1: Introduction It’s a long post so get comfy, bring your favorite beverage, take a deep breath and now lets start! Let us try and understand what each of them really is and how do they differ. Certainly, if you are reading this you are a newbie so we will not go much in the complicated working (for now) of each and every component but we will try to just keep it simple and create just an intuitive understanding of each device. Fig. 1 : RL Circuit Consider you’re getting a 12V from a battery and you need to power your Arduino which needs 9V. So you need to drop your voltage by  12v-9v= 3v you then recall the Ohms Law ( V=IR ) an

Hello Friends, I am Sharing my next project which based on PIR Sensor and 8051 Microprocessor. Sensor Based Automatic Targeting System for Border Area is an automated gun target and firing system if found an object within a range of sensors. The project is primarily based on PIR Sensors, Microcontroller, and a wireless transmitter and receiving units using FSK. The Project is required because till today, the border is protected by Iron Spike wires, and a watch tower containing a person continuously flashing the light over the border area day and night. Those persons are fully responsible for any intrusion.This project will not fully remove the responsibility from their soldiers, but minimize the responsibility and human mistakes on the border. The sensors will sense any living object inside the range, provide the s/g to microcontroller, in response, microcontroller generates the code on the site and send to the watch tower where the receiver receives the code, provides code to micr

This is a very simple project.Only OLED is new in this project OLED is upcoming Technology.That's why I am Sharing this Instructable. What is an OLED? OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and so are thinner and more efficient than LCD displays(which do require a white backlight). OLEDs are not just thin and efficient - they can also be made flexible (even rollable) and transparent. OLED vs LCD OLED displays have the following advantages over LCD displays: Improved image quality - better contrast, higher brightness, fuller viewing angle, a wider color range and much faster refresh rates. Lower power consumptionSimpler design that enables ultra-thin, flexible and transparent displays Better durabil
