I've had some experience using Arduino Uno, but now tried to use Mini for the first time, and have gotten stuck.
I planned to use the Uno to program the Mini, so I hooked up 5V, GND, TX, RX and Reset to the Uno (plugging TX->TX and RX->RX, not crossing), and a led to pin 13. The only difference from the setup on the ArduinoMini page was that I did not remove the chip from the Uno.
After trying to upload a sketch, the led blinked, as if it was resetting, but the board failed do work (I tried uploading Blink first). After several more tries, it worked, but then trying to upload a different sketch failed again.
Any ideas? Do I need to remove the chip from Uno for the board to work as a programmer for the Mini?
(It's probably something obvious, and I'll look like a real noob
Thanks in advance.
