7.7 Lab Experiments

7.1 Build a circuit that causes an LED to glow using a 5 second turn-off delay.  Instead of a push-button switch, you can simply momentarily connect two wires together.

7.2 Build a circuit that emits an audible tone and causes a pair of LEDs to blink. The LEDs should blink on and off at a rate of “approximately 1 Hz (first LED on for 1/2 second, then the second LED is on for 1/2 second, then repeat) and the audio tone should be between approximately 200 Hz and 2 KHz. Submit a video demonstrating this functionality.
