A student did the above wiring for Exercise 2. Based on the wiring, will this crystal ball circuit work? Justify your answer. Note 1: The LCD is labelled slightly differently, but the pins are the same as the ones you used in class. Note 2: The element labelled SW2000 is the tilt switch. Example Answer: One error in the circuit is a missing resistor on a LED, this can cause the LED to burn out very quickly. To solve this error, we need to either connect a resistor from ground to the cathode, or from power to the anode leg of the LED.
