Beginner Electronics Project: Simple Oscillator with 555 Timer and Speaker in Astable Mode EVLOG, 7

I have grand ideas of making a fully operational VCO oscillator and using 555 Timers as the primary driver. Is that practical I don t know, but here is a video of testing it out. Link to 555 Timers: Link to Breadboard Kit: They are relatively cheap and I hope to use them for more future projects Let me know what you think. Any comments are always welcome as I m new to this level of electronics and can always use more advice. Thank you
