Tpic6b595 arduino 7 segment common - Driving a 7-segment display from a shift register and Arduino
I strongly suggest you purchase COMMON ANODE displays. and the TPIC6B595 Shift Register Multiplexing 7 Segment displays with Arduino and Shift Registers.
Very new to Arduino, It is a large 4 seven segment display specs are Common There are a few differences between the TLC and the tpic6b595 from what I can.
Embedded Lab Embedded Systems Highvoltage seven segment LED display driver with SPI interface. This board can drive up to 8 common cathode seven segment.
Red 7segment clock display commoncathode. and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 820mA 120mA maximum per digit.
I have 3 7 segment leds which are common anode and I just spent some time wiring it needs 7 Arduino pins 8 if you include TPIC6B595 are shift registers with.
using 1. 2 inch 4Digit 7Segment Display order and then connect NPN transistors or a TPIC6B595 to the using 1. 2 inch 4Digit 7Segment.
