| Aug 4, 2015 at 4:04 | comment | added | James Waldby - jwpat7 | What are the rated voltages of the servos and the sensor? How do you know the servo is not getting enough power? To hold down electrical noise, power the sensor from pro-mini Vcc instead of from motor battery if sensor is rated at 5V. Minimizing electrical noise is one reason to use two separate power supplies. The motor driver and the pro-mini need to have a common ground but don't have to have common Vcc | |
| Aug 4, 2015 at 2:28 | comment | added | Builder | It worked but servo is not getting enough power so it gets lost many times and does not move at right time so left-right-center readings from u-sonic sensor not correct and car hits wall or stops in the middle. | |
| Aug 4, 2015 at 2:05 | comment | added | James Waldby - jwpat7 | How well does it work in the following situation? : Jumper off; motor-power battery connected to Ext_Pwr; separate Arduino-power battery connected to pro-mini RAW (or 5V power supply connected to pro-mini Vcc); a ground pin on the shield wired to a ground pin on the pro-mini | |
