We demonstrated the reliability, robustness, and precision of this communication in six studies. In our solution, an Arduino measures response latencies after being signaled the start of a trial, and communicates the latency and response back to the PC over a USB connection. These boards connect to standard experimental software using a USB connection and a virtual serial port, or by emulating a keyboard. We propose using open-source Arduino microcontroller boards as an inexpensive and flexible alternative. Response boxes and data acquisition cards are precise, but expensive and inflexible, alternatives. ![]() ![]() ![]() Often keyboards are employed to collect buttonpresses, but their imprecision and variability decreases test power and increases the risk of false positives. Latencies of buttonpresses are a staple of cognitive science paradigms.
