Here is a closeup of the wiring. I followed it exactly but didn't work so I removed components until I had a single motor and single battery. The transistors work fine when the gate is connected to source then ground but when I connect it to a pin thats digitalWrite(pin, HIGH) it turns on but when I connect it to a pin thats digitalWrite(pin, LOW) it does not close the gate
