SAMPLE PROJECTS - OSCILLATOR MODE:

These project ideas are models or samples. Once you understand the full capabilities of the UT5, you can adjust

these details and add all the bells and whistles you wish.

1. CODE PRACTICE OSCILLATOR

(Basic Model for ALL 555 Audio Tone Generator projects)

 Use R6 for Jumper 1.

 Install Jumper 2.

 C1 = .22 or .33 uf.

 R3 (pitch control) = 100K pot.



Connect key in series with + DC line.
