 Making a decision may require more than just one or two facts. When this happens, another operator is needed to combine the facts together to make a conclusion. In the last example word equation, you actually might not be floating if just those two condtions are true.

 Data is transmitted between digital circuits using changes between high and low voltage levels. A change to high can mean a signal for the value of `1`. The change down to low can mean a signal for the value of `0`. One of these signals, a pulse, can represent a binary digit, or _bit_. Combining several digital signals will form a binary number which can represent some type of data, such as a [number](/types/number) or [text character](/types/string).

 It's not necessary to use a separate pin to transfer each bit of a digital number. Each bit of a number can be written out on one pin in a sequence. Once all of the bits of one number are written, the bits of the next number are written in a sequence too. The receiving device needs to properly assemble the bits to form a value. It also needs to know how many bits each number will have so it can start to assemble the next number. This method of sending and receiving data is call _serial data_ transfer.

 In order for a ``||input:on touch||`` event to detect a touch properly, the untouched pin's [sense value](#sense-value) is set as the touch [threshold](#threshold) for the sensor connected to it. A _threshold_ is a value, that when reached, will cause something to happen. Depending on what is connected to the pin, either nothing or some larger object, the pin will read sense value based on the amount of [capacitance](/learnsystem/pins-tutorial/devices/capacitors) measured at the pin. This is, of course, a different value when the pin or sensor object is touched and untouched.
 
-To properly detect a touch, the sense level the untouched case must be known. A sense level for a touch will be somewhat greater than the untouched level. When a program is started, the pins set for touch events are calibrated for the untouched sense levels. This is brief process where the pin input is read several times to find a reasonable value of sense level for when the pin, or something connected to it is untouched.

 Calibration automatically sets a threshold (the minimum sense value) for what is considered as a touch. You may need to recalibrate your touch input if there is a change of sensor or in the environment. If you connect a different sensor object to a pin without restarting your program, your touch event may indicate a touch when there isn't one or it may never detect a touch at all. Also, if the temperature or humidity changes significantly, the electrical characteristics of a sensor might change. You may observe over time that it might detect a touch before your finger reaches it, being too sensitive, or that you have to press on the object more firmly, for a longer time before the touch is detected.
