Newbie ? Using Serial monitor / UNO Tx&Rx pins

-

hello all, hope use forum aid in self learning of uc , programming in general.

please advise:
1. how use serial monitor send commands ?
2. kind of commands send, list ?
3. , these commands transmitted tx pin, right?

with these questions, hope connect serlcd 16x2 directly tx pin , use serial monitor send 1 command @ time feel controllin serlcd ? guys think ? have not tried yet on own i'm waiting serlcd show up.

1. how use serial monitor send commands ?

you don't. use serial monitor send data. data may mean arduino, or not.

2. kind of commands send, list ?

you don't send commands.you send data arduino may interpret command. list arduino sketch.

3. , these commands transmitted tx pin, right?

the data is, yes.

you can't that. if serlcd connected tx/rx pins, pc can't connect. if pc connected, serlcd can't use same pins.

you connect pc tx/rx pins, , use newsoftserial connect other pins serlcd connected to. serial.read tx/rx pins, , use newsoftserial instance talk serlcd.

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
