To avoid parasitic noise at the start I add a sequence "0, 6, 14, 22, 30, 38, 46, 54, 60, 68, 74, 82, 90, 98, 106, 114, 122," at the start of "const unsigned char sample0 [] PROGMEM". As a precaution, perhaps it is better to attack the transistor with a 150 Ohms connected to the base.
Wow, it looks so easy. Can we save the voice in this arduino and get another power supply for activate the arduino and the speaker? How much the voltage ?
Amazing tutorial, thank you! could I ask a question? there is a way for an outside button/trigger instead of that on the motherboard? for example in a BLASTER, this will perfect to get the sound clicking the trigger, the only problem is that in your video I can see some LAG from the trigger to the sound, maybe a lightweight sound will be more rapid.
Tx Ahmed and Roland Jolivet, now I know how to do this. I just got this idea today to make a countdown timer for a girl with cerebral palsy that can not speak, however you can use a technique called voice cloning to synthesize a similar sounding voice based on her utterances, that is the sound she can still make. And so when that works I put it all on a microcontroller with sound samples from "Ten" to "Zero" and then she will have her own countdown timer with her own voice to for example 🔥 🚀 Or just listen to herself speaking.
Just wondering can you use something else as a substitution for BC547? or like would it be okay to use op amp for a substitution. Is BC547 working as an amplifier ?
Hello.
