Need help use LM358 circuit with Arduino micrcontroller ADC input
I want to implement a LED fault compensation circuit. When a LED has failed, there will be an open circuit and no current will flow through the string. Hence, a zero current will be sensed at the RS and it will be feed backed through ADC to the microcontroller. The microcontroller will take response.
but I can't get the signal at ADC, please advice my circuit any wrong.
