Microcontroler board question (50$ robot tutorial)
« on: December 17, 2007, 06:49:53 PM »
Im ready to build the controller board for the 50$ robot.
Unfortunately when I got to the part shop they didn't have
the exact resistance listed in the part list.

So the part list has 340 ohm and 1.62K ohm
Both of them were unavailable..
( So I got 330 ohm and 1.6K ohm both of them have a +- 5% tolerance)

So here is my question, do I need exactly those resistance values or
can I use resistance close to the mentioned values.

Thanx everyone!

thats good enough. the photoresistors arent equal either, so if you have more than 2 you might want to use the 2 closest ones

GL and dont cheap out on teh programmer cable

Thank you very much.

And, what do you mean about the programmer cable?
It came with the programmer, I brought the AVR ISP mark II from Amtel.
I dont think I went cheap lol
