What means 'R1 and R2' on the Protoshield v.4?

hai,

What means 'R1 and R2' on the Protoshield v.4?

Dion

R generally means resistor. What shield are you using?

R1 is the pull up resistor on the reset line. R2 is a series resistor on the programming lines to act as protection in case there is an input / output conflict with what you connect it to.

The Arduino Duemilanove with 32K Atmega 328. But I would like to know how much Ohm the R1 and R2 are?! ;D

I didn't ask what Arduino. Do you have a link to the shield?

Ohh, sorry. The proto shield v.4. http://www.rtfa.net/wp-content/uploads/2009/01/lady_ada_protoshield_v4_rtfa.jpg

It is like I said

R1 is the pull up resistor on the reset line. R2 is a series resistor on the programming lines to act as protection in case there is an input / output conflict with what you connect it to.

With R1 = 10K R2 = 1K

jon-dion you have to be more specific about who's Protoshield v.4 you are talking about.

From the photo you posted you can see the colours on the resistors showing the values are 1K and 10K.

All thanks! :D
