From the experiment 1 and 2, I construct circuit by using eagle 6.0 software to do schematic and run the simulation to make sure the components value are suitable to make sugar detector circuit. After the construct using the schematic are suitable and function based on the result from the experiment. From the schematic circuit, I continue to construct PCB circuit using eagle 6.0.
picture 1 : sugar detector schematic circuit
picture 2: PCB circuit
picture 3 : etching the PCB board from picture 2
The circuit already etching using etching powder, then by using multimeter to troubleshoot each wiring connection because sometimes after etching,the connection are not properly connected. Lastly,apply the component and soldering . after finished soldering,test the circuit for the functioning.
