On chips like this with multiple elements, all the inverters on the chip are the same, cmox you can pick whichever one makes the layout easiest. Get all 3 oscillators happy before continuing. Or wire in a pot variable resistor to control the pitch. We used a different integrated circuit the chip last week to build our amps; it had only one circuitry block in it, a single analog amplifier the right-pointing triangle on the schematic.
This tutorial shows how to build oscillators on a solderless breadboard. BTW, most chips do different things and have different pin-outs.
Oscillators can also control other oscillators, making cjos complex tones. All 3 oscillators signals are now mixed together, out to the amp. In addition to changing them manually, we can also use one oscillator to control another oscillator.
You should be able to hear the first oscillator switching the tone of the second oscillator back and forth between low to high. Check each oscillator out one at a time, by listening to each output separately. Ov course, you might have something different by now…. Handmade Electronic Music Routledge, ; chapter Tom Bug’s BugBrand electronics page. You can get some pretty complex sounds with cmoe a few basic building blocks, repeated a few times.
CMOS – CMOS – Six inverting Schmitt trigger
Start with what you had for the last circuit, 401066. Once we start stringing circuits together, one circuit controlling another circuit… oh, boy.
After experimenting and finalizing your design, you can transfer it to one of our Oscillator boards to make it more gig-worthy. 440106 using variable resistors and start monkeying with the rate of the first oscillator, then the frequency of the second… then both.
The 3 k resistors on the right are the mixer resistors. So we have oscillators, and we can change their frequency by changing the values of either the resistor or capacitors. Replace the resistor with a photocell.
So you can get 6 oscillators out of one chip.
SIMPLE • DIGITAL • FAST
We want to mix all three oscillators together. A sweet setup would be 3 pairs of FM oscillators with all three outputs mixed together… speed controls on the slow oscillators, photocells on the fast ones, individual volume controls… you get the idea. You can also change the capacitor value… swap in some different ones and see what happens. SO those are some basics: We can do the 4016 thing here.
Oscillators produce AC signals, which we can amplify and hear as tones.

Or, hold the two resistor leads in your fingers and squeeze to change your skin resistance. This is one of those cmso that omits the power connections, and just shows the basic circuit building blocks although it does show the pin numbers. Data sheets also often have sample schematics that can help get you started using a new chip.
