PWM ADC_Vminus, V_Offset * 255/500,100 ' PWM ADC offset voltage
PWM ADC_Vref, V_Span * 255/500,100
Close the Debug Terminal.
Open StampPlot macro sic_pc _incubator_manual.spm.
Connect and plot.
Monitor the temperature to ensure it is reading correctly at room temperature.
Control of the ADC resolved temperature range – Upper and Lower. Note: The
BASIC Stamp reads these only in the initialization section of code. If changed,
press the RESET button on the Board of Education, or disconnect and connect
on StampPlot.
Control of the heater and the fan.
Indication of current minimum and maximum temperatures.
Button to reset the minimum and maximum temperatures.
