Demonstrate the function of a logic chip on a bread board.
Use the SN74AC08N (Quad AND gate) along with the DIP switch and pull-up or pull down resistors to show the function of an AND gate. Show the output by hooking it to an LED with a 330 ohm resistor in series.
Use 5V from the power supplies.
DLD.MOVMicrocontroller
Get a simple program onto the microcontroller (counting program, anything that turns some LEDs on).
microcontroller hw.mp4IR Sensor
Use the diagram from the comparitor slide to experiment with the IR sensor and the LM393 comparitor in your kit. Try to get the IR signal to have the comparitor turn an LED on/off.
Remember, the IR led in the sensor needs a resistor (like any LED) and the output of the comparitor is an "open collector"
IR sensor mechatronics hw.mp4AtoD Assembly
Get the AtoD assembly program working and displaying the conversion from ADC0 (pin 23) on PORTD with LEDs.
