555 timer circuit

Made a 555 timer circuit.

I didn’t have a 1M ohm pot, so used a 100k pot instead. At first, I used 0.01uF capacitors, but the slowest frequency I could get was about 1KHz. (due to my wrong 100k pot) with the resistors that I had. I switched the 0.01uF capacitors out with some bigger ones (take longer to charge/discharge). I used 0.22uF capacitors and got the frequency down to around 16 Hz. (perioud = 60ms. 1/0..06 = 16.666)

I made a little video:
