In this article, we are going to make our own remote-controlled device using SONY SIRC remote protocol. In the previous article, we have learned the basic pattern of this protocol and now we will use that in our circuit. We’ll use PIC12F675 micro-controller and mikroC Pro for the PIC compiler. Read more
In this article, we will understand SONY SIRC Protocol, and we will decode this protocol. Afterward, we’ll find out the command and address. Only after getting a clear idea, you can make your own decoder yourself. In this article, we are getting an idea only, and in the next article, Read more
In this article, we are going to make our own control card for coffee vending machines. This machine is nowadays very common in shops and restaurants. Small businesses can be started with this machine. Here let’s make a simple functional control card for the coffee vending machine. About the coffee Read more
Max232 is one of the most popular RS232 communication ICs in the electronics arena. Straightforward circuit and very easy to use too. Anyone can implement the circuit within few minutes. But there are some issues I found in products. If you are using the MAX232 IC as your product and Read more
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 with Viper12A. ***Warning: An electrocution hazard exists Read more
From hobbyists to professionals transformerless power supply is one of the common power supply design everyone wants to do. This type of power supply has both advantages and disadvantages.
