Ok so first off, please excuse this very cringe-worthy border, but I couldn't be more excited to announce that I'll be starting my very own building series!!! So essentially, every week, I'm going to be filming short tutorial like videos on building cool projects (such as a digital to analog converter, robots to help with your day-to-day activities, or even programming projects..etc.) and posting them on the "#buildwithRushi" page (on the menu). The first "episode" will be out on the 25th of April, and I'll most likely be continuing to post a new tutorial every Saturday! But it'll be very very fun!! Hope y'all enjoy it and be sure to look out for updates on the page every Saturday! I'm providing a little sneak peak of what I'll be building on this post, but I'll be explaining and demo-ing it using my Arduino UNO board on the buildwithRushi page! Check it out then!! Ok anyways, lets get back to business. Lately, I have been really interested in sound systems. Not just because I have been listening to music all day lol, but because I really really want to know what is behind a speaker, and how it converts digital bits of information (like 0s and 1s) to analog waves. Its just insane to think about how some sort of electronic system can transform bits of information to the cool sounds we heard through our headphones. How does this happen tho? It is all because of a Digital to Analog converter, or a DAC. What is a Digital to Analog Converter?A digital to analog converter is a system where a digital signal is converted to an analog signal. DACs are found in sound systems such as CD players, or sound cards (to hear your computer's audio). Audio signals are stored in digital form (MP3, for example), and a DAC converts it into an analog signal for us to hear it. Now, there was a time where we actually didn't really need a DAC. This was when the analog signals were created when the needle of the record player made contact with the record grooves. It would cause an electric analog signal, which was then transmitted to the speaker, so we could hear it. How does a DAC work?
I'll get into more details about DAC functionalities next Saturday, April 25th! Lets goo! Stay safe, stay home, contribute, and wish you happiness and peace!
