Use fritzing to draw all the circuits covered in the presentation in schematic and breadboard view. Use a breadboard and real components to prototype the circuits on slide 58, 61 and 64. Document your progress and understanding of the circuits and concepts covered.
Use the circuits on slide 61 as a reference to design a circuit that would turn on the LED when light is presented on the LDR and turn off the LED when there is no light presented on the LDR (notice it is the inverse function of the circuit). Prototype the design using a breadboard and the necessary components. Document the concept behind your design and the prototype.
I’m going to swap the LDR and the potentiometer.if there is no light on the LDR, the resistance increases and the voltage between B and A increases.That will allow to the led to work. if light is presented on the LDR, it lowers the resistance and will lower the voltage between B and E. so that , the led won’t work.
