Lesson 6 Part 6 - How To Fix Just About Anything Electronic!
🕑 Added 2023-03-02 03:58:51 +0000 UTCTwo projects for you to build today, one digital and one analog. Learn how the 7555 provides pulses to a Johnson Counter, and view it's function. Johnson Counters, or "Ring Counters" are used in many pieces of equipment, and it's very important to understand how they operate. Build and experiment. The second circuit is found in audio and RF application, the J-FET amplifier is extremely versatile and easy to build. Build this circuit on a breadboard and experiment with values and frequencies to get a better understanding of the way it responds to component changes. Add both of these circuits to your reference book, they will come in handy in the future.
