This is a simple Turbidity meter with a Light Dependent Resistor and a Laser
Materials needed -
1. LDR
2. Laser Pointer
3. 33k Resistor
3. Dark tube/Box (We used a black pvc pipe)
4. Arduino + usb cable
5. Wires
6. test tubes
Tools -
1. Soldering Iron + Solder
2. Glue Gun
3. wire cutter/stripper
1. Connect one leg of the LDR ground on the arduino . The other leg of the LDR will go to analog input 0 (Any of the analog inputs can be used.
2. Connect one leg of the resistor to +5V on the arduino. The other leg of the resistor will go to the same analog input as the LDR (A0 in this case). This forms a potential divider.
