I have make the 50$ robot, it was working great. I add three LED to make some light effect and all works great. Yesterday i receive my rs232 shifter and make the UART interface work. OK now it's my question.
How i can plug my three LED, the 2 servo for the wheel, an other servo for my brand new sharp ir rangefinder and my uart interface ? I need 6 output pin, the ATMega8 have only 5 and 2 of them are for the UART... how i can add output ? adding an other microcontroller ?
Thanks for your help guys
