UART Communication


I'm trying to establish a UART-Communication with my MKR1000. I connected pins 13,14 and GND to a TTL-232R-PCB (

Then i upload the code with the Arduino IDE and change to the Com-port where the TTL is connected to. But the Serial Monitor of that port doesnt show anything.

My program is very simple.

void setup() { Serial1.begin(9600); }

void loop() { delay(100); Serial1.println("hoho"); }
