One of the very useful transformerless power supplies using Viper12A IC can be used in many applications. It is sufficient to run micro-controllers, sensors, displays, relays, and so on. With very few numbers of components, we can get a reliable transformerless power supply using Viper12A...
Basics:
To generate PWM(Pulse Width Modulation) both analog and digital circuits can be used. But using a micro-controller is much easier than other methods. To generate PWM, the micro-controller has a built-in PWM module. But if there is no such PWM module then how can you generate PWM? Yes, in...
SONY SIRC Protocol:
There are three types of SIRC protocol, 12, 15, and 20bit types. All these types have a command and device word. The 20-bit version has only 8bit extended words. Within the bitstream, each word is sent LSB first like this pattern below:
The frame timing is based on...
The basic of comparator:
Comparator is one of the mode of Op-Amp circuit. It is pretty simple in configuration like this image below:
The output of the comparator is high if the non-inverting input voltage is higher than the inverting input pin. And the output is low if the non-inverting pin...
