Hi there !
I been not able to work on my robot for a long time for some reasons and also not on electro-tech, but finaly I have finished it but it has just one problem that output of L293D is just 50mA. I am attaching a schematic of my robo.
The LEDs connected to MCU pins ( in alternate polarity to the same pins ) are the input pins for L293D and the LDR sensor section is shown far right. I know that these LEDs connected directly to MCU drop volatage so I tried removing them but did'nt help. I connected LEDs just for indication that at least digital part is O.K. Please help me I selected this robot for my collage project and have to submit in a week !
I am using 12V adapter for power supply for testing and then will switch to +9V battery.
