SUMMARY
The discussion centers on troubleshooting an LED flasher circuit using the LM358 operational amplifier. Users reported difficulties in getting the circuit to function correctly, particularly with resistor values and connections. The omission of a 100k resistor between the V+ and non-inverting input was highlighted as a potential issue, especially in circuits without split power and a center ground. Proper wiring and resistor values are crucial for the circuit's operation.
