Sir I make a project using esp32 and 4 channel relay. The project works fine on after uploading but after power interruption or when reset button is press it doesn't work and there is a single led glowing in dim light on the relay. Please help me how to solve this problem.
Make sure there is a enough volts on VCC of relay. I had same issue when tried to connect 5V relay to 3.3V esp output(I didn't knew about that in the moment)
Sukses selalu semoga ilmunya berkah, salam kenal mohon izin ikut nyimak videonya.
