In the previous article, we have learned about the basic operation principle of solar charge controller and besides, we have seen a working circuit with both analog and micro-controller based on/off charge controller. In this article, we are going to learn how to make a PWM charge controller using that Read more…
To generate PWM(Pulse Width Modulation) both analog and digital circuit can be used. But using a micro-controller is much more easier than other methods. To generate PWM, the micro-controller have a built-in PWM module. But if there is no such PWM module then how can you generate PWM? Yes, in Read more…
In this project we will learn how to identify faults in single phase line and additionally we will send the fault notification to a mobile number as SMS. In this project we will use PIC16F73 micro-controller and SIM module as GSM module. We’ll also know why we need single phase Read more…
