Many embedded systems has some challenges in common like:
Throughput, Response, testability, Debugability, Reliability, Memory Space, Program Installation, Power Consumption, Processor Hogs, Cost, schematic diagrams are not layouts showing where the parts are located on the board.
There are two voltages, low 0 and high 1.
Signals usually have name. The bubble only inverts the signal.

Semiconductor=chips, To attach the semiconductor you use the pins, chip manufacturers should provide a data sheet. 0 is ground (GND) or low. 3-5 Volts is called VCC (Voltage connected to collector) or high. Signals have name. The bubble is to invert. The chip has a power pin (VCC) and a ground pin. Usually those pins doesn't appear on circuit schematics. Capacitors stores a small amount of electricity.

Each chip has a power pin (VCC pin), connected to a high signal (VCC) and a ground pine, low. One problem is that some chips uses more power at some time than others.A capacitor is a device that stores a small amount of electricity, like a minuscule rechargeable battery.open collector outputs, allows you to attach the outputs ofseveral devices together to drive a Single signal.tri-state outputs: high, low, float.
