PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

But it is slower since the data is sent one nibble at a time. 4-bit mode is often used to save I/O pins, while the 8-bit mode is used when speed is necessary. For this tutorial, we will be using the 4 ...

This tutorial demonstrates how to control the backlight of a 16x2 LCD display using an Arduino Uno and a button. The provided script allows you to toggle the LCD backlight on and off with a button ...

An eForth for Arduino UNO/Nano implemented in C..ino sketch file can be openned in Arduino IDE, no programmer to overwrite bootloader needed. Has 16-bit cells and stacks. Can read/write Arduino GPIO ...

For example an spi display or TV-out (using the TV-out library, probably on a second arduino). Reason for me to ask, I’ve got a Yamaha PSR-S500 with defective display, new displays are around ...

LCD.h is the file including all the fixed constants and the local methods used to manage the display. Also useful to create a good documentation of the display features local methods. You should ...

We might think that an AVR microcontroller – e.g. the ATMega328p adopted by the Arduino UNO boards – has the sufficient number of pins to manage an alphanumeric LCD. In a complex industrial machine ...

[Andy Brown] wrote in to show off the TFT LCD adapter he’s been working on for connecting inexpensive displays to an Arduino Mega. These TFT LCD screens can be picked up on eBay for a few ...
