Well I will try to give you as much information as possible. Am am trying to build a circuit that will produce a clock signal for a counter. However this clock signal should be triggered by a change in light for a photo transistor or photo resistor. I have VTT7122 photo transistor and VT906 photo conductive cells available.
Per say:
A cup is resting on top of the photo transistor. When I lift the cup or object it will create a clock signal that will increment a counter by one. The table will be have plenty of ambient light to ensure that the photo transistor work properly.
Sorry I did not specify earlier, but i would like to make it using only IC's if possible. IF this is not possible what micros are good to work with that you have had good experience with.
Any help is greatly appreciated.
