Newbie with arduino problems

I have athome a vera edge with a lot of sensors.

now i wil tray to bild some things, and i found thise wonderfull site.
I have order some componets to build a weather station.

But i wil tray to understand what happens in the arduino file.
I have instal the software for the arduino, and the file of the solar weather station out the build tap of this forum.

Now i tray this; Serial.print("temperature"); with Serial.begin(9600); to see what happens,but i see strange characters in the serieel monitor of the arduino software. is this normale or do somthing wrong.
by a test file works it good and see i good and excepet valuels.

I hoop that you understand me, and sorry for my bad englisch.

make sure that your serial monitor is set to the same baud rate (9600) in your code

Hello bulldoglwell,

thanks for your replay. but i have the baudrate at 9600 in the serial monitor.

I have tray all baudrats and baudrate 115200 see i the valuels.
i don't no why but it works

I am happy.

thanks for the help.

Did you flash the sketch with the correct speed setting for the MCU? Try to change it to 16 Mhz or 8 Mhz, if you already set the MCU to 16 Mhz before. If the frequency setting for the MCU is not correct this breaks the uart timing.

Oke,

and how can i change this.
I can't find it.

Just choose another Arduino board in the Arduino IDE. Pro Mini 5V 16 Mhz or Pro Mini 3.3V 8 Mhz.
