[Tom] needed 8 displays for a project. He wanted to to control them over I2C, and was trying to reduce cost. Some vendors make I2C controllable seven segment displays, but they cost about $10 each.

I’ve talked about HD44780 displays before – they’ve been a mainstay of microcontroller projects for literal decades. In the modern hobbyist world, there’s an elephant in the room – the sheer variety ...

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 ...
