Lonely Binary

The TK53 at an angle: a tall black seven-segment digit block with white segments and a dot, standing on a black board, lonely binary printed below it, and a six-pin right-angle header lying over the lower end of the board between two round mounting holes, its pins labelled GND-1, VCC-2, NC-3, LATCH-4, CLOCK-5 and DATA-6.

74HC595 Segment LED

One 0.8-inch red seven-segment digit with a 74HC595 shift register under it, on a TinkerBlock board: three wires set all eight segments, one byte per digit, a 1 lights a segment. Common cathode, 150 Ω per segment, VCC on your board's logic supply, and no chaining: the 595's serial output is not connected.

Every pin and part: the 74HC595 and its eight 150 Ω resistors under the digit, the NC pin that goes nowhere, and the chip's serial output that is not connected, which is why the board does not chain.
