It has a storage latch associated with each stage for strobing data from the serial input (D) to the parallel LED driver outputs (QP0 to QP11). Again shift registers can come to the rescue. The 74HC595 is a serial-to-parallel shift register or SIPO (Serial In Parallel Out) device for increasing the number of outputs from your microcontroller. There are also the tpic6b595 shift registers with high current (sink only) outputs. The HEF4894B is a 12-stage serial shift register. A led driver will automatically keep a constant current, regardless what kind of led it drives. It is a very important (and often missed) thing to remember while multiplexing, as you will want to change the PWM values each cycle (or at least synchronize these changes with the PWM cycles). This device is used in conjunction with a microcontroller, with only one dedicated line. Uses a clock interrupt. My question is, since I have to toggle the pin high to turn it off does that mean when I pull the pin high my +9V will have a direct connection to my +5V that is powering the shift register from the UNO? 8 Resistors for the LEDs 1 Shift register for the columns 1 Driver array for the rows 8 Resistors for switching the driver array 1 microcontroller 1 clock source for microcontroller 1 prototyping board 1 power supply Hook-up wire Specific Parts Used Here For this instructable I used the following: 64 green LEDs (Mouser part #604-WP7113GD) The MAX6971 is one of a family of 12 shift-register-plus-latch-type LED drivers. low-current power 12-bit shift register designed for use in systems that require relatively moderate load power, such as LEDs.
