ESP32 interfacing with 16x02 LCD with 74HC595D shift register
Budget: ₹1,500 – ₹12,500 INR
I got 2 boards,
1 - board with ESP32 with shift register.... , working on TTL level 3.3V
2 - 16x02 LCD board with 5V backlight supply and 5V VCC supply...., but to be interfaced with 3.3V of shift register output
board is ready, shift register tested and working ok... but unable to display any data on LCD, need support for the same only for coding with arduino IDE to show data on LCD
