2. FLOW CHART PROGRAM
Sebelum membuat program alat pengatur suhu pasteurisasi, perlu dibuat flowchartnya terlebih dahulu :
Dengan menggunakan flowchart tersebut, maka logika pemrogramannya menjadi lebih mudah. Jika suhunya kurang dari setingan, maka heater akan
ON. Jika suhunya melebihi batas atas setingan, heater akan OFF.
