Copy of Arduino Code
1. Accelerate all motors from start to 25% in 3 seconds. //celerate(4,0,25,3)
2. Run all motors at a constant speed (25% power) for 2 seconds. //motorSpeed(4,25)
//goFor(2)
3. Run all motors at 20% power for 2 seconds. //motorSpeed(4,20)
//goFor(5.5)
4. Reverse all motors. //reverse(4)
5. Run all motors at a constant speed (20% power) for 2 seconds. //motorSpeed(4,20)
//goFor(2)
6. Brake all motors. //brake(4)
