I'm doing a school project where a prompt gives you a random word to spell via an audio player & you have to answer on a laptop, then depending on whether you get it right or wrong, a green or red light blinks.
The only issue is that I have no idea how to set it up, and I really need your help.
I have an Arduino Uno R3, a Keyestudio Audio Amplifier, a Keyestudio MP3 Audio Player, and a single breadboard.
Could someone please show me where each part goes via a diagram or something.
Sorry if this is sloppy, I'm in a rush
The Arduino selects an audio track to play, plays it, waits for the user to type what he/she heard onto the PC keyboard , then compares the results, expected versus actual, and switches a led accordingly. Is that it?
I suggest starting with Serial Input Basics - updated then work out how you are going to associate the written form of the sound with the sound track so you can check the spelling. Progress from there. Have you already got an SDcard or similar with recorded test words for the player?
Thanks at least for the honest admission. But it obviously prompts the question: why not? Have you missed or slept through all the presumed classes so far? It's a fairly complex project assignment for a total beginner, so it's puzzling that you apparently don't have a clue how to start!
It's unlikely that anyone here is going to coach you from scratch. As a next step I recommend you 'fess up to your teacher and ask for some more guidance.
Then come back and we might be able to help - although as you are "in a rush" don't get your hopes up.
Do what those of us who were alive before there was an internet. READ. Go to the library after school and read until closing.
What we can do is give you pointers to some books we think are helpful. Here are my favourites.
Yes, you do. You are in a class, given the information, and exercising that information by doing the assignment. The purpose of school is for learning. Listen to your instructor, read the material, do the exercises.
What you are really saying is, "Do my school work for me,"
Listen, read, experiment as fast as you need. Only YOU control your destiny.
To get your project up and running, start by wiring the MP3 audio player to the Arduino Uno R3. Connect the TX pin of the MP3 player to the RX pin (pin 0) of the Arduino and the RX pin of the MP3 player to the TX pin (pin 1) of the Arduino. Connect VCC and GND from the MP3 player to 5V and GND on the Arduino, respectively. Then, connect the Audio Amplifier to the MP3 player’s audio output, and wire the amplifier’s output to your speaker.
For user input, you can use a push-button or keyboard interface. If you’re using a button, wire one side to a digital pin (like pin 2) and the other side to GND, with a pull-up resistor between the input pin and 5V. For feedback, connect green and red LEDs to digital pins 9 and 10, each in series with a 220Ω resistor. These will blink based on whether the user answers correctly or not.
If you’re looking to power your audio amplifier reliably, especially for higher-power setups, consider using a power supply similar to the one in this 400W DC-DC converter project. This high-power converter can be used to power your audio amplifier, ensuring that it has enough current to deliver good audio output without instability.
We recognize the urgency you're now expressing, but it's important to clarify that a delay or lack of initiative in starting the project on your end does not constitute an emergency on ours. We plan our time and resources carefully to maintain quality and fairness across all commitments. While we are willing to assist, we cannot and will not allow a sudden rush caused by prior inaction to disrupt our existing priorities or compromise the integrity of our process. Your timeline cannot override the responsibilities we’ve already undertaken.
Besides all the other responses, please tell us how you will get a random word on your audio player and how your laptop will know what that word is so it can compare the type answer to to random word!
char words[][6] = {"Give", "Never", "Up", "Gonna", "You"}; // list of random words
int randomNumber[] = {1, 3, 0, 4, 2}; // pseudo-random array of numbers
void setup() {
Serial.begin(115200);
for (int i = 0; i < 5; i++) { // list of five words
Serial.print(words[randomNumber[i]]);
Serial.print(" ");
delay(1000);
}
}
void loop() {
// empty
}
Maybe the weekend starts on Thursday for some students, but if OP is able to take an extended weekend break from this "rush" project, then that only proves my previous assertion:
Starting to wonder if I should call missing persons... or they are on summer holiday and stuck on an island with a washed-out bridge and the ferry port is out of fuel... or something like that... probably will need a late-night before school starts (next) Monday.
