Basic Arduino Robot Car Kit + Motor driver L298N H-Bridge module

//Arduino code: int L1 = 6, L2 = 7, L3 = 8, L4 = 9; // Pins connected to Motor driver L298N H-Bridge module void setup() { // initialize the digital pins we will use as an output. pinMode(L1, OUTPUT); pinMode(L2, OUTPUT); pinMode(L3, OUTPUT); pinMode(L4, OUTPUT); (9600); } // the loop routine runs over and over again forever: void loop() { forward(500); halt(2000); reverse(500); halt(2000); rightSpin(500); halt(2000); leftSpin(500); h
