Hi folks! I'm just starting out with circuit design and I'm trying to create a master LFO that uses a potentiometer to control the rate. I also want to have several secondary LFOs that operate at divided rates based on the master LFO. I'm a bit confused about how to set up the secondary LFOs off the master. Should I use a chip like the CD4040 for frequency division, or can I just tweak the capacitor and resistor values for each LFO to get the desired frequency? Any guidance would be greatly appreciated!

If you need square waves, a 555 timer in astable mode together with a CD4024 or CD4040 could work perfectly. But if you're looking for triangle waves across all outputs, just know you'd need a different setup for that.
You might want to consider using an oscillator divider chip like the CD4060. It allows you to pick off different frequencies from its divider chain, which could simplify things for your design!
Thank you! I'll definitely look into the CD4060.
I'm actually hoping to stick with triangle waves for everything.
