MiniDraw (stepper version)

thingiverse

This Project is an innovative design based on:\r\nhttps://www.thingiverse.com/thing:3259401\r\n\r\nIt employs two budget-friendly 24BYJ stepper motors instead of servo's.\r\nPrint the stepper housing upright. Infill all parts with at least 50% for optimal stability and strength. The steppers are controlled by Arduino Nano, driving an ULN2003.\r\n\r\nExample:\r\n//NanoFull step mode\r\n//512 >> 360 degrees 1.4 step/degree\r\nint M1A = 2; int M1B = 3; int M1C = 4; int M1D = 5;\r\nint M2A = 9; int M2B = 10; int M2C = 11; int M2D = 12;\r\n\r\nint t=3;\r\nvoid setup() \r\n{ \r\n pinMode(M1A, OUTPUT); pinMode(M1B, OUTPUT); pinMode(M1C, OUTPUT); pinMode(M1D, OUTPUT); \r\n pinMode(M2A, OUTPUT); pinMode(M2B, OUTPUT); pinMode(M2C, OUTPUT); pinMode(M2D, OUTPUT); \r\n\r\n} \r\n void loop() \r\n{ \r\n\r\n//Motor 1 \r\nfor (int x=0; x<20;x++){ \r\ndigitalWrite(M1A, HIGH); digitalWrite(M1B, HIGH); digitalWrite(M1C, LOW); digitalWrite(M1D, LOW); delay(t);\r\ndigitalWrite(M1A, LOW); digitalWrite(M1B, HIGH); digitalWrite(M1C, HIGH); digitalWrite(M1D, LOW); delay(t);\r\ndigitalWrite(M1A, LOW); digitalWrite(M1B, LOW); digitalWrite(M1C, HIGH); digitalWrite(M1D, HIGH); delay(t);\r\ndigitalWrite(M1A, HIGH); digitalWrite(M1B, LOW); digitalWrite(M1C, LOW); digitalWrite(M1D, HIGH); delay(t);}\r\nfor (int x=0; x<30;x++){ \r\ndigitalWrite(M1A, HIGH); digitalWrite(M1B, LOW); digitalWrite(M1C, LOW); digitalWrite(M1D, HIGH); delay(t);\r\ndigitalWrite(M1A, LOW); digitalWrite(M1B, LOW); digitalWrite(M1C, HIGH); digitalWrite(M1D, HIGH); delay(t);\r\ndigitalWrite(M1A, LOW); digitalWrite(M1B, HIGH); digitalWrite(M1C, HIGH); digitalWrite(M1D, LOW); delay(t);\r\ndigitalWrite(M1A, HIGH); digitalWrite(M1B, HIGH); digitalWrite(M1C, LOW); digitalWrite(M1D, LOW); delay(t);}\r\n\r\n//Motor 2\r\nfor (int x=0; x<20;x++){ \r\ndigitalWrite(M2A, HIGH); digitalWrite(M2B, LOW); digitalWrite(M2C, LOW); digitalWrite(M2D, HIGH); delay(t);\r\ndigitalWrite(M2A, HIGH); digitalWrite(M2B, HIGH); digitalWrite(M2C, LOW); digitalWrite(M2D, LOW); delay(t);\r\ndigitalWrite(M2A, LOW); digitalWrite(M2B, HIGH); digitalWrite(M2C, HIGH); digitalWrite(M2D, LOW); delay(t);\r\ndigitalWrite(M2A, LOW); digitalWrite(M2B, LOW); digitalWrite(M2C, HIGH); digitalWrite(M2D, HIGH); delay(t);}\r\nfor (int x=0; x<30;x++){ \r\ndigitalWrite(M2A, LOW); digitalWrite(M2B, LOW); digitalWrite(M2C, HIGH); digitalWrite(M2D, HIGH); delay(t);\r\ndigitalWrite(M2A, LOW); digitalWrite(M2B, HIGH); digitalWrite(M2C, HIGH); digitalWrite(M2D, LOW); delay(t);\r\ndigitalWrite(M2A, HIGH); digitalWrite(M2B, HIGH); digitalWrite(M2C, LOW); digitalWrite(M2D, LOW); delay(t);\r\ndigitalWrite(M2A, HIGH); digitalWrite(M2B, LOW); digitalWrite(M2C, LOW); digitalWrite(M2D, HIGH); delay(t);}\r\n}\r\n\r\nhttps://youtu.be/S53riJs3i6o
