Waterbath base on microcontroller 89S51

Waterbath is a laboratory equipment used to stabilize the temperature of the sample through a temperature controlled water medium, where the temperature, which is between 30 0C to 40 0C by setting the timer 1 minute to 15 minutes.
In order to maintain the desired temperature stability, first heat the water by using a heater. Then once the desired temperature is reached, the heating will be controlled heater. When the temperature setting below the heater will turn on and if on top of the heater temperature setting will die, so the temperature will be maintained at the specified temperature.
