Temperature controlled fan using AVR Microcontroller (ATMega16)

Introduction: You may have seen so many applications of temperature control and indicators using different micro-controllers, microprocessors or other control devices. But what is the actual use of these temperature regulators is presented here. It controls the fan speed continuously, as the temperature varies. It is not a simple ON-OFF type control that activates the … Read more Temperature controlled fan using AVR Microcontroller (ATMega16)

Frequency Measurement and Pulse Width Measurement using Microcontroller (AT89C51)

Frequency Measurement Pulse Width Measurement using Microcontroller and Circuit designers and developers need different measuring equipment, such as digital multimeter, CRO, DSO, frequency counter, logic analyzer, etc. to test their circuits. When designing any PWM oscillator or generator or have generated any waveform, it is necessary to measure either the frequency or the time period. … Read more Frequency Measurement and Pulse Width Measurement using Microcontroller (AT89C51)

Intelligent Train Engines

We know that the Indian rail network is the largest in South Asia and perhaps the most complex in the world. There are so many local trains, fast, fast fast, passenger, goods …. etc. and several multiple procedures. However the schedule is perfect, it cannot be retained. And that’s why the train accidents are more … Read more Intelligent Train Engines
