MAX7219 Interfacing with 8-digit 7 Segment Display and PIC16F877A

MAX7219 interfacing with 8-digit Seven-Segment Display using pic microcontroller

In this tutorial, you will learn how to interface the MAX7219 8-digit 7-segment controller IC with PIC Microcontroller. MAX7219 has a built-in circuit to control 8 seven-segment displays. Firstly, it communicates with microcontrollers over SPI communication. Hence, only three pins are required to control 8 seven-segment displays. Secondly, we can use MAX7219 to control dot … Read more

74LS93 4 Bit Binary Counter Pinout, Working and Examples

74LS93 counter example with seven segment display from 0-9

74LS93 or SN74LS93 is a 4-bit binary counter. Counters have a major role in every electronics device. The output of the counters can be used in multiple devices as pulse counting or for generating interrupts, etc. Counters come up in two form Asynchronous and Synchronous counters. Both these types of counters use the flip flops … Read more
