-### Procedure
+## Procedure
+
+- **3 bit Binary Weighted Resistors**
+1. Connect the components as mentioned below:
+L1-L5, L4-L6, L3-L5.(For eg. click on 1 and then drag to 5 and so on.)
+2. Click on 'Check Connection' button to check the connections.
+3. If connected wrong, click on the wrong connection. Else click on 'Delete all connection' button to erase all the connections.
+4. Set the Resistance (R) value (1 Kohm - 10 Kohm).
+5. Set the Feedback Resistance (R<sub>f</sub>) value same as the Resistance (R) .
+6. Set input voltage (V<sub>in</sub>).
+7. The IC is given proper bias of +12V and -12V to V<sub>CC</sub> and V<sub>EE</sub> respectively.
+8. Intially B<sub>2</sub>B<sub>1</sub>B<sub>0</sub> are set to 000.(B<sub>2</sub>B<sub>1</sub>B<sub>0</sub> are 3 bit input)
+9. Now note the output voltage and click on 'Add to table' button.
+10. Change the B<sub>2</sub>B<sub>1</sub>B<sub>0</sub> and note the output voltage and click on 'Add to table' button.
+11. Repeat the experiment for another set of resistance value.
