The basics of oscillators what they are, what they are used for, and it shows a couple of demo circuits with a sine wave oscillator and a square wave oscil. Even at that low speed, your square wave will look closer to a triangle wave The LM339 will not have that problem.

ATtiny microprocessors can use an internal RC oscillator or an external crystal oscillator External crystal oscillators are more accurate, but require two pins For these low pin count devices it can be beneficial to use the internal oscillator. Oscillators are important in many different types of electronic equipment For example, a quartz watch uses a quartz oscillator to keep track of what time it is An AM radio transmitter uses an oscillator to create the carrier wave for the station, and an AM radio receiver uses a special form of oscillator called a resonator to tune in a station There are oscillators in computers, metal.

Notes It has been my experience that students require much practice with circuit analysis to become proficient To this end, instructors usually provide their students with lots of practice problems to work through, and provide answers for students to check their work against. They consist of an amplifying device, a transistor, vacuum tube, or opamp, with some of its output energy fed back into its input through a network of resistors and capacitors, an RC network, to achieve positive feedback, causing it to generate an oscillating sinusoidal voltage.
