i want to decrease connections and components from this circuit , as i want the output to be connected to an Arduino
also " LF357 " opamp doesn't exist near me
[CENTER]i already made an AVR USBasp programmer but when i connected it to PC it gives error :bang: :bang:
(i made this programmer with the same circuit before and it was working :thumbsdown:)

Hello , i have a project " Fire Fighting Robot " that i should do without any microcontroller 8-O
just by logic gates ( combinational circuits + sequential circuits ) :roll:
here is the map
**broken link removed**
am using 3 IR sensors (Right - Left - Front)
i already finished the wall...
Hi , i have a project of " Fire Fighting Robot " :roll:
and i'm having a problem in the proximity sensor that i want to use many IR sensors instead of using ultasonic ( very expensive ) but the maze area will be affected by :
- The light level of the surrounding in the testing area
- The room...
i made a new usbasp with ATmega8 and when i connect it to my lap and read it i got that error
" error: programm enable: target doesn't answer. 1 "
then i connected pin 25 to GND and still not working
