2.3
Figure 2.1 showed an example of circuit in which an LED is turned on and off by turning on
and off a switch.
microcomputer.Figure 2.4shows the connection of LEDs to the microcomputer on the board.
Figure 2.5 shows a conceptual diagram of the connection. In the case of (a) in Figure 2.5,
the signal output from pin P10 is at the high level. Therefore, no current flows through the
LED and the LED is off. In the case of (b) in Figure 2.5, the signal output from pin P10 is at
the low level. Therefore, a current flows through the LED, and the LED goes on. The
switch in the microcomputer can be operated by a program that controls the microcomputer.
