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: Engine ON (System is in HORN State): The system will generate selected duty cycle at PWM pin  where Horn is connected.   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% Increase/Decrease of switching frequency using two switches (GPIO Input):  After powering up the system, the system will start with factory calibrated PWM of 30% duty cycle.  The switching frequency can be increased or decreased using two switches.  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:  If temperature is higher th...

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....

“Use it up, wear it out, make it do, or do without” E-Waste The term “electronic waste” or “E-waste” elucidates discarded electronic devices, which are destined for reuse, resale, salvage, recycling or disposal. A general insight into the electronic waste generation cycle will make us realize the fact that this is an alarming problem, which needs to be addressed as soon as possible, on a global scale. This chart shows the exponential growth of electronic waste generation in an under-developed nation, which is expected to reach about 1.8 million tonnes by the year 2025. If this seems alarming to you, then the fact that India alone produced a whopping 1.7 million tonnes of e-waste in the year 2014 alone, may come as a shock to you. Ranking 5 th  on the list, made by UN, of highest e-waste generators, India’s maximum e-waste comprised of household equipment. In terms of per capita waste generation, India’s reports are less alarming (not in top 10 ranks), but...
