Lab Demo 1 – Soldering & Circuit Debugging Techniques IDE of Keil4 V3.a 35

Demonstration Detail Soldering Probing signal using CRO Tracing signal path using multi-meter IDE of Keil4 V3.a 36

Marking Scheme Finish all the soldering jobs correctly (1.5) Correct use of components (including correct orientation and polarity ) (0.5) The LED power indicator light is on (0.5) Soldering with proper soldering skills (the amount of volcano shape and ball shape joints) (0.5) Demonstration of circuit debugging skills by CRO and multi meter (1.5) Use multi meter to check whether J7 pin1 is connected to pin3 of L293(U6) (0.5) Probe the output (Pin3) of LM78T05 to show the voltage level (0.5) Probe the XTAL2 (CLK) on the board to show the frequency and period (0.5) IDE of Keil4 V3.a 37
