DIYbio Orbital Shaker

INTRODUCTION This is version 2.0 of our DIYbio orbital shaker, packed with even more exciting features. We'll be adding in a wealth of additional information, videos, and step-by-step assembly instructions very soon. All the electronics are identical to those found in the original model, as is all the Arduino code. The electronics diagram can be viewed above in the images, while the Arduino code will be provided below for your reference. Be sure to check out our prototype on Thingiverse for valuable hints on assembly: https://www.thingiverse.com/thing:2633507 Until we get some more detailed documentation up for this version, feel free to explore and learn. The SketchUp file is included, containing both the original prototype and the new version. It also features some designs not included in V 2.0 that you're welcome to use or modify as you see fit. Video of it in action: ARDUINO CODE Arduino sketch used: // Simple Stepper Motor Control // // by Achim Pieters, www.studiopieters.nl // // // Defines pins numbers const int stepPin = 7; const int dirPin = 8; int customDelay,customDelayMapped; // Defines variables void setup() { // Sets the two pins as Outputs pinMode(stepPin,OUTPUT); pinMode(dirPin,OUTPUT); digitalWrite(dirPin,HIGH); // Enables the motor to move in a particular direction } void loop() { customDelayMapped = speedUp(); // Gets custom delay values from the custom speedUp function // Makes pulses with custom delay, depending on the Potentiometer, from which the speed of the motor depends digitalWrite(stepPin, HIGH); delayMicroseconds(customDelayMapped); digitalWrite(stepPin, LOW); delayMicroseconds(customDelayMapped); } // Function for reading the Potentiometer int speedUp() { int customDelay = analogRead(A0); // Reads the potentiometer int newCustom = map(customDelay, 0, 1023, 300,4000); // Converts the read values of the potentiometer from 0 to 1023 into desired delay values (300 to 4000) return newCustom; }
