Learn how to easily adjust the contrast of a 1602 LCD display using Arduino. In this quick tutorial, I’ll show you a simple trick to control the contrast electronically, without relying solely on the ...

However, if you want a fixed contrast level then you can replace the potentiometer component with a resistor-diode setup as shown below. This gives a solid DC level (0.65/0.7 V) at the input of the Vo ...

As promised in the first part of this article, now it is time to see in detail how we can use the Alphanumeric LCD Display in our Arduino sketches. The idea beside this project is to give a simple ...

[Tobie’s] part of the hack is to use an Arduino and a few buttons as the controller. It’s easy to set up and we think the breadboarded controller approximates the size and weight of an LCD ...

It powers the Arduino mini pro which drives the 1.8″ LCD screen and actuates the optoisolator which is responsible for triggering the camera.
