Title: testing the LDR and DC motor performance
Objective: Testing the LDR performance and motor movement
Content/Procedure: LDR performance is testing by adjusting the variable resistor.The reading value of LDR is is take in two position (when LDR is on the light and when LDR is on the shade)
and observe the DC motor movement.
Result :
FIXED RESISTOR
