Performance

Oscilloscope measurements quantify the execution time of a simple digital pin toggle across multiple Arduino boards. Results show that faster CPUs complete the operation in fewer microseconds, though instruction overhead varies by architecture. The data confirm a near-linear relationship between CPU clock speed and pin toggle performance.

Evaluation of EEPROM Programmer performance on Arduino. Overhead from digital I/O measured, and oscilloscope traces confirmed datasheet timing. Active polling of the READY/BUSY pin reduced write latency while maintaining reliability. Sequential write/read verification showed consistent integrity. Future work includes endurance testing, retention studies, and comparing Arduino boards with different clock speeds.
