Resistor Chip Arrays
Product Name: DIY Welding Kit for Single Chip Four Digit Clock
Product model: TJ-56-637
Working voltage: DC5V
Board size: 79 * 70mm
Description:
This kit uses the STC11F04E microcontroller, which is a single clock/machine cycle (1T) microcontroller produced by STC. The instruction code is compatible with the traditional 51 microcontroller, but the speed is 8-12 times faster than the traditional 51 microcontroller, adding an independent baud rate generator and eliminating the timer.
Key function:
S1: Modify the time and alarm clock to enter the setting mode.
S2: Select the modification position to enter the setting mode.
S3: (Short press) Switch between hour minute display, minute second display, and exit settings. (Press and hold for about 3 seconds) Reset the time to 0:00:00, reset the alarm to 0:00:00, and turn off the alarm.
Setting mode:
Press S1 or S2 to enter the settings, and S3 to exit the settings. The first round is time setting, the second round is alarm setting (alarm can only be set for hours and minutes), and the third round is alarm switch setting (OFF to turn off the alarm, on to turn on the alarm).
Setting sequence: (time) minute bit (time) minute ten bit (time) hour bit (time) hour ten bit (alarm) minute bit (alarm) minute ten bit (alarm) hour bit (alarm) hour ten bit (alarm) hour switch (OFF/on) (time) minute bit
