The study was conducted to design and develop a microcontroller-based tissue culture growth. Specifically, it aimed to: design and construct a microcontroller circuit for tissue culture growth room-, develop a software that will interface the components of the growth room using assembly language-, conduct test runs for the growth room in terms of providing the desired temperature, light intensity, and photoperiod, and determine the cost of the system. The microcontroller controls the operation of the whole system. It was composed of power supply, integrated circuits, relays, crystal oscillator, LCD, and the microcontroller chip. The main component of the microcontroller was the PIC16F877 microcontroller chip where the software of the system stored. Four light stands and one culture cabinet were placed inside the growth room. Twenty four pieces of 48" 40 W cool-white fluorescent lamps were used as the light source. The air conditioner and heater were used to supply the temperature requirement. The ceiling fan was used to circulate the air inside the growth room. The software of the system was developed using Assembly Language. The program was composed of different subroutines such as Read Key, Do Key, Do Msg0, Do Msg, Do Light, Do Time, Disp Time, Chk Hour, Read ADC, Get Temp, Chk Thermo, Do Hot, Do Cold and LCD subroutine. These subroutines are also broken down into subroutines that perform specific functions in the program. The software controlled the operation of the microcontroller. It is capable of instructing the operations such as supplying the required photoperiod, light intensity, and temperature needed. The evaluation of the microcontroller focused on controlling light intensity, photoperiod, and temperature inside the growth room. The microcontroller was tested in different photoperiod and light intensity combinations. It was observed that the actual time and set time of turning ON and OFF were almost the same. The number of lamps turned ON by the microcontroller was observed to be equal to the set number of lamps. Also, the system was evaluated by comparing the temperature read by the microcontroller and the measured temperature inside the growth room. It was observed that the temperature read by the microcontroller and the measured temperature of the growth MOM was almost the same.
