PID温度控制，用10K的NTC采样，温控精度为0.1

Keeping alive a KRUPS cofee maker with Arduino WARN!! does not has PID to control temperature The LED flashing sometimes fail NTC pin to +5V, Another pin to A0, A0 (PullDown resistor) to Gnd of 22000Ohms (22K - orange,orange,orange) For led

PIC芯片，具有采样，PWM，NTC温度，PID控制，MPPT功能(PIC chip, with sampling, PWM, NTC temperature, PID control, MPPT functions)
