All Error and Error and Accidents

Today I was attaching two ultrasonic soonar to the Voice Controlled robot car. I attached and connected the circuit. Then I edited the codes and uploaded to the arduino. But the sonars were not working. The car was colliding with obstacles. I checked the connections, it seemed ok. so I edited the code. Now only the back sonar was working. so I edited the codes again. Again no working. I changed the sonars from one wire system (trig and echo same wire) to two wire system. and edited the code. Again not working. The bot was colliding a lot. I was afraid that the bot can be damaged. Now I checked the whole connections again, but no result. I edited the codes a lot of times. But all was ending in failures. I was so confused. And it was almost 2 hours. I was becoming hopeless. But I decided to check another time. I was checking the wire connection. All the connection was perfect but one. I now found it, the ground pin of front sonar was not connected. The wire was placed to the next row of the ground pin. it was so difficult to see and realize it from a distance. I connected it to the exact row now. and again tested the bot. This time it was not colliding with obstacles. I was so happy that can not be written here. after all, I did it
