Read the voltage drop across a high-value resistor at room temperature. There are random fluctuations proportional to the temperature and resistor value. You can use these fluctuations to generate unifromly distributed random numbers. https://en.m.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_noise https://en.m.wikipedia.org/wiki/Johnson%E2%80%93Nyquist_nois...
