I see. I have a 555 clock built into my breadboard. Hmm.. A counter. My friend mentioned about using a counter too because he said something about, when the chip counts down, e.g. if I put my DIP switch to 0100 (which is '4' in DEC), it will blink 4 times for the short signal. I think I can use...

I think I have to somehow find a way to split the signals. :( I'm not very sure about this. I will have 2 LED bulbs in the system, one to represent short signals, and another for long signals. Hence, for "2" (as an example), I will have 2 blinks for LEDshort signal, 3 blinks for LEDlong signal.

Oh. No. I am doing D1A of the project as of now, which requires me to "read input from 4-bit DIP switch, RESET button (which is the push button I have now) and design the circuit." You may refer to the picture for more information above. :) Yes, my input is binary. The 7-segment display comes...

I see. Sorry for being unclear in my explanation and description above. For example, if I want to output a "2" (in DEC notation), I will push the 4-bit DIP switch to 0010. The DIP switch will output its signal to the chip. Do you need me to show you a picture or the circuit diagram of my 4-bit...

I am not sure about the deeper logic as of now. >< But I believe there is a deeper logic as this project doesn't look simple to me. :(

Hi mfb. I shall respond to your questions here: Yes. I will have to push the button which is already present in the circuit in order for the circuit to output a reading, and hence, display the result. The pushbutton is just a switch, I believe. The DIP switch will continuously give an output...

Homework Statement Hi everyone. I am currently embarking on a Morse Code project which involves building a circuit to display Morse codes, eventually displaying the Morse code with a 7 segment display. I am currently stuck at the first stage as I am not sure of what to do, i.e. what chips to...

Thank you rude man, for your replies. I am studying this topic at the basic level, I guess, as I am a Year 1 student doing electrical engineering. I shall keep your responses in mind when I wire up my circuits. :) Thanks again!

Hi Svein. Thank you for your reply. In the end, my group used a verifier sort of thing at the receiver side to weed out false frames so the correct frames can be received and processed at the receiver end. :)

Hi NascentOxygen. Ah I see. Thank you! :)

Hi rude man. Thank you for your answer. I will take your suggestion into consideration when I design my system. Just wondering, what do you mean by "terminating the line at the receiving or transmitting end with that impedance"? By impedance, you mean complex resistance, like in an AC circuit...

Homework Statement I am currently embarking on a project where I have to build a communications system which can take in an analog voice signal, translate it into digital signal, and send it across to the receiver where the original voice gets recovered and it can be played back using a...

Homework Statement I am currently embarking on a project which requires me to design a system where I can transmit voice over a distance, by inputting an analog voice signal on one end and then recovering the voice which I input on the transmitting end at the receiving end. The general design...

Hi MohammedRady97. Yes, programming is a very useful skill, especially for electrical engineering, as coding helps in telling your chips what to do in a system. Learning programming also teaches you some managerial skills, for example, taking a huge problem and breaking it down into smaller...

I see. Yupp, I meant that. Haha. That was the diagram shown in my lecture notes, so I can link to it better. :) Yes, and thank you so much for your help! :D I should be fine with my assignment now.
