I am building a 555 astable timer circuit for a course which must match the BPM of a song. The song has a BPM of 104, which requires a timer frequency of roughly 1.733 Hz.
(the green wires go off to the left onto another breadboard, which looks as follows:)
It is hard to see, but the 0.01µF capacitor goes to pin 5 of the 555 timer.
The values used in the circuit as follows (measured using a LCR meter): R1 = 5.5kΩ R2 = 38.5kΩ Ctotal = 10.02 µF
The problem is that the circuit produces a frequency of roughly 1.5, far off the from the desired/predicted frequency of 1.733. 5V Power is being supplied to both rails, the chip has been replaced, but to no avail. Here is a picture of the simulated circuit in LTspice:
Is this due to some limits of the 555 timer at frequencies nearing 1Hz or due to some miswiring on my part?
