I was making this project and after numerous hours worth of efforts, I was able to finish it. However, on powering up the project through a 9V battery (also tried two serial Li-ion 3.7V batteries as well). The PIC powers up fine but the motors don't power up. I also tried manually shorting 5V to the inputs, but no success. The results were same. I get 0V voltage reading on the motor outputs of L298. What to you think is causing the problem? Here is the schematic of L298 wiring used in the project. I also assure you that the rest parts of the project are working fine, only the L298 unit is faulty for some reason. Please help me debug it to get this LFR to work.
