An 8-digit DIP switch
An 8-digit DIP switch, from left to right 1~8, the maximum value can reach 128, when the switch is not dialed, the state of the switch is all up, that is, on the ON/DP side, when the DIP switch is close to Female header the number When one side is in the down state, then the corresponding relationship between the numbers on the switch and the actual decimal number will be explained in detail.
1. If you want to dial the number 1, you can directly dial the 1 on the switch, because from the figure, it can be seen that 1 corresponds to the zero power of 2, and the zero power of 2 is equal to 1 in decimal.
2. If you want to dial the number 10, you can dial down 2 and 4 on the switch. As can be seen from the figure, 2 corresponds to the first power of 2, which is equal to 2 in decimal; 4 corresponds to the third power of 2, which is equal to decimal.
