Planning Laboratory

Laboratory 1.0: designing and soldering a logic probe. Prototyping  electronic circuits

Lab 1.1 [10 Set]

1.1.3. Laboratory prototypes

This preliminary laboratory activity is for learning to solder electronic components using basic tools. There are many books and web pages to instruct you on this important skill for prototyping electronic projects.     

Project tutorial: Designing a logic probe simple instrument

Let us conceive a simple instrument: a logic probe, to visualise logic values and detect digital signals.

- High level in a red LED. Low level in a green LED.

- Tri-state or floating voltage in a yellow LED.

- Oscillating digital signals in a white LED.

- CMOS and TTL compatible.
