Diagram: I have represented the Arduino RX pin as a diode and resistor just to think about the circuit, but the actual hardware inside is probably different. What is looks like: Here is what the ...

This paper adopts Arduino DUE and Raspberry Pi for organic light emitting diode (OLED) lifetime measurement. Using digital-analog converter (DAC) port of Arduino DUE output voltage to control the ...

MAX4936 and MAX4937 high-voltage, octal transmit/receive (tx/rx) switches integrate clamping diodes to isolate low-voltage receive paths from high-voltage transmit signals.
