A Wheeled Robot Car Explores Its Surroundings on Its Own. Two Affordable Stepper Motors 28BYJ Handle the Movement, Controlled by an Arduino Nano and Two ULN2003 Chips. The Vehicle Runs on Three AA Batteries (4.5 V) Placed at the Bottom of its Chassis to Provide Weight. A Switch Hole is Drilled into the Chassis for Easy On/Off Access. The PCB Has Space for Additional Inputs and Outputs, Allowing Users to Customize Their Robot Platform as They See Fit. The Design Prints Easily Without Supports. Here's an Example Arduino Code: //Nano Full Step Mode //512 Steps Equal 360 Degrees, with 1.4 Steps per Degree int Pin0 = 9; int Pin1 = 10; int Pin2 = 11; int Pin3 = 12; int Pin4 = 2; int Pin5 = 3; int Pin6 = 4; int Pin7 = 5; int t=3; void setup() { pinMode(Pin0, OUTPUT); pinMode(Pin1, OUTPUT); pinMode(Pin2, OUTPUT); pinMode(Pin3, OUTPUT); pinMode(Pin4, OUTPUT); pinMode(Pin5, OUTPUT); pinMode(Pin6, OUTPUT); pinMode(Pin7, OUTPUT); } void loop() { //Around Axis for(int x=0; x<500;x++) { digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); delay(t); digitalWrite(Pin0, HIGH); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(t); digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); delay(t); digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, HIGH); delay(t); digitalWrite(Pin4, HIGH); digitalWrite(Pin5, LOW); digitalWrite(Pin6, LOW); digitalWrite(Pin7, HIGH); delay(t); digitalWrite(Pin4, HIGH); digitalWrite(Pin5, HIGH); digitalWrite(Pin6, LOW); digitalWrite(Pin7, LOW); delay(t); digitalWrite(Pin4, LOW); digitalWrite(Pin5, HIGH); digitalWrite(Pin6, HIGH); digitalWrite(Pin7, LOW); delay(t); digitalWrite(Pin4, LOW); digitalWrite(Pin5, LOW); digitalWrite(Pin6, LOW); digitalWrite(Pin7, HIGH); delay(t); } //Reverse for(int x=0; x<500;x++) { digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, HIGH); delay(t); digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); delay(t); digitalWrite(Pin0, HIGH); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(t); digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); delay(t); digitalWrite(Pin4, LOW); digitalWrite(Pin5, LOW); digitalWrite(Pin6, HIGH); digitalWrite(Pin7, HIGH); delay(t); digitalWrite(Pin4, LOW); digitalWrite(Pin5, HIGH); digitalWrite(Pin6, HIGH); digitalWrite(Pin7, LOW); delay(t); digitalWrite(Pin4, HIGH); digitalWrite(Pin5, HIGH); digitalWrite(Pin6, LOW); digitalWrite(Pin7, LOW); delay(t); digitalWrite(Pin4, HIGH); digitalWrite(Pin5, LOW); digitalWrite(Pin6, LOW); digitalWrite(Pin7, HIGH); delay(t); } //Around Wheel for(int x=0; x<500;x++) { digitalWrite(Pin0, HIGH); digitalWrite(Pin1, LOW); digitalWrite(Pin2, LOW); digitalWrite(Pin3, HIGH); delay(t); digitalWrite(Pin0, HIGH); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, LOW); digitalWrite(Pin3, LOW); delay(t); digitalWrite(Pin0, LOW); digitalWrite(Pin1, HIGH); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, LOW); delay(t); digitalWrite(Pin0, LOW); digitalWrite(Pin1, LOW); digitalWrite(Pin2, HIGH); digitalWrite(Pin3, HIGH); delay(t); } }
