This project measures the input voltage using an Arduino Uno and displays it on a 16x2 I2C LCD screen. It uses a simple voltage divider circuit to safely read voltages up to 12V. The Arduino reads an ...
Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...
I am an experienced embedded software engineer (and Professor) and I was shocked at how difficult this was. Using these devices on Arduino with the Arduino IDE "just works." Pain points for ESP-IDF ...
