About the project

This 4 digit seven segment display module is controlled using 74HC595 Shift Register. The module uses a single standard common anode display.

I created this circuit because I have many salvaged parts.

This time I want to present an 7-segment four digit display controlled by two 74HC595.The LEDs are connected in the common anode configuration; this module is useful in electronic assemblies with Arduino or other development boards where you need to display numeric data, such as e.g. temperatures. For each digit, there are pins A, B, C, D, E, F, G, and DP, respectively, for the next point after the digit. Note: the real display must contain those two dots in the middle and another one in the upper right corner (it does not appears on the 3D model).You have access to the cathodes and the anodes of the display using 4 pins placed on side of the module.

The representation of letter segments is universal. The 4-digit red LED display module, each with 7 segments, is useful in electronic assemblies where numbers must be displayed. Being 4 digits is useful for displaying time or to be a timer. The module has a common connection for each digit of the LED anode.

Thank you!
