Project Euler

I started solving Project Euler problems with Python as a COVID hobby. I solved 216 problems between June 2020 an April 2023. In September 2025 I began to redo solved problems in C++ and executing them on embedded systems. Below I document the embedded solution times and hardware used. Given variations in runtime, I only benchmark to two significant digits. See my Microcontrollers section for technical specs. Below is example code for how I measure the execution time.

void loop(){
    parameter = Serial.parseInt(); //waits for input
    if (parameter>0){
        runtime = micros(); //grab the start time
        for (int i=0,i<100;i++){
            //compute the problem here, 100 times
        }
        runtime = micros() - runtime;
        Serial.println(answer);
        Serial.println(runtime/100.0);
    }
    parameter = 0;
}
