It’s been quite a while !!! I have finally dropped all my extra-projects to take good care of my botdream.com.
Still need to finish the 2nd H-Bridge circuit to power up the DC motors. Next I will need to create the hardware interface between PC and modules (H-Bridge 1 and 2, temperature, distance sensor, etc). For that I will use a Microchip PIC 16F628A that will connect to the PC Serial port to communicate with applications and by the other side to an I2C BUS that is connected to the modules!
