Hi everyone,
I am using a seeeduino XIAO and I have flashed a code to read the temperature value from the temperature sensor LM35 connected to the pin1 of seeeduino. Now, I want to power the seeeduino and temperature sensor using the output from a DC-DC converter AP62300WU-7. The circuit diagram of the whole circuit is below:
when i connected the seeeduino, the yellow LED is blinking. it was not blinking when connected to the laptop. does anyone know why this is happening or what this indicates?
