Hello!
I am new with arduino... Please, I need help, I have arduino ethernet and I want to connect two Leds, one sensor of movement, LCD, and serial port.
I think the port serial connection is good. My problem starts because I have to connect the Leds pin (called 9 and 8) the sensor Pin (called 2) I don't have more Out to connect the LCD. Is tru this?
can I move the pins of the sensor or the Leds for connect the LSD? Because I have Ethernet and this esquematic is for UNO
Anybody confirm the schematic serial is ok?
and the general schematic is good, or I have ton change somting?
