it appears that adhesive electrodes have been attached to the leaves of the recently-empowered plant and connected directly to analog inputs of an Arduino Uno. From there, the text tells us that ...

It should also work on an Arduino Mega (AtMega2560), Gemma/AtTiny board, and most other AVR processors running on the Arduino framework. The Arduino Due, Arduino 101, and Teensy boards are not ...

4 and 19 pins are used to adjust the display contrast through a resistor. I use a 1 Mega Ohm variable resistor. Acceptable contrast ~270kOm.

This study uses Arduino Mega microcontroller as the main control, proximity sensor to detect the presence of glass, and the HC-SR04 ultrasonic sensor as a determinant of high water levels and an SD ...

is instead an Altera Cyclone EP1C12Q FPGA development platform with a VGA display (LCD form iPad 2), a PS/2 QWERTY mechanical keyboard, a battery, and a few ports. While the OneChipBook-12 is sold as ...
