Making Of Vehicle Horn System

Automotive Horn System is a standalone module which is controlled by Microcontroller by generating switching frequencies that can be calibrated. The following are the preconditions for Horn Operation:

  1. Engine ON (System is in HORN State): The system will generate selected duty cycle at PWM pin  where Horn is connected. 
  2.  Engine OFF: (System is in Calibration State): The switching frequency or Duty cycle can be increased or decreased by 5% through two calibration switches w.r.t default value ie. 30%
  3. Increase/Decrease of switching frequency using two switches (GPIO Input): 
  4. After powering up the system, the system will start with factory calibrated PWM of 30% duty cycle. 
  5. The switching frequency can be increased or decreased using two switches. 
  6. Thermal and safety feature: In horn state, system will check the temperature value using analog input to avoid thermal breakdown of Horn system as per below conditions: 
  7. If temperature is higher than 500 and less than 1000 decimal value, then system will switch to 10% duty cycle on PWM output to avoid thermal breakdown of the circuit.
  8. If temperature is higher than 1000 decimal value, the system must switch OFF the PWM output to zero. 
  9. Under normal conditions i.e. temperature value less than equal to 500, system will operate as it is and must generate calibrated PWM output.

Menu List on 20x4 LCD

MENU ON LCD(20x4) USING ARDUINO API In this project, I had made a menu on 20x4 lcd display using data structure in arduino. you will see how to perform many functions with 4 button(ENTER, NEXT, PREV, BACK) depending on the situation, such as going up the menu and brightening the LCD. Each menu has few submenus and also their sub-child which call various function to perform related task for clear understanding see below pictures. Followings are the software required to make this project. 1. Proteus for simulation of arduino hex file. Note:- how to simulate hex file in arduino please see  how-to-make-quick pressed led 2. Arduino for coding. Now Visit the given drive to get all the files. For any queries comment below. Thank You

Quick Pressed Led Animation Module

How to make a quick animated similar to touch led using Arduino ?. I think this is a very good project for the beginners to learn Arduino as well as to design PCB for this project and make it a fully customized Module. Let's get started... Before I proceed to explain these project you require the following thing. Arduino Uno RGB Led(common anode) Resistor 330ohm, 10k ohm Soldering iron Male strip -1 Push Button-1 Proteus and Arduino software 1. INSTALLATION OF SOFTWARE AND SIMULATION 1. Install the latest  proteus  in your PC 2. Add  Arduino library  in Proteus. 3.After installation creates a new  project  and makes the schematic as follows. 4. Install  Arduino  in your pc. 5. Add TimerOne library in Arduino.(Sketch ->Include Library -> Manage Libraries -> 6. Now write the  following code in Arduino  then Compile and generate  hex file . #include <TimerOne.h> const int button = 8; const int yellow = 9; const i

Best Ways to Download Udemy Courses on PC (Offline)

Udemy allows you to download videos on the android app for offline viewing, but in the case of PC, Downloading depends upon the instructor whether they allow it to download or not which is very rare. In the case of Mobile downloading you can only play the video in Udemy player or there are some cases in which when you update the app your offline encrypted downloaded video gets erased damn too frustrating. In this blog, I am going to tell you some of the best options to download Udemy courses on a computer. Either you can download one by one or by a single click you can download the whole video. Also, downloaded video is not encrypted and you can play it on any video player. Mine is VLC :P Method 1(Master Method): Udeler Udemy course downloader If you looking for some open-source software to download all or multiple videos in one Udemy course, there is open-source software Udeler to help you download all of your courses in one go. You can even specify the video quality and which v
