I haven't had the chance to write a decent post on my current IY for a few weeks, I would say unfortunately but not so as I've been having a blast!
I've been getting to play with all sorts of hardware that I had no idea about until recently. I got to spend a few days researching methods of creating movement through electronics, magnets and pneumatic (not the thing you get from being too cold, I made that mistake too).
The gif (pronounced with a hard G) above shows one of my little contraptions that I was extremely excited to build. It mostly took me a bit to interpret how the wiring of our actuators matched to the inner coils, after that it was 6 wires to a H-Bridge and 4 pins to the arduino to give signals of direction essentially. Here's the code I've been using as a super simple demo just to test the wiring is working (If you haven't played with an Arduino then go get one, super cheap, super easy, super open-source electronics)

#include <Arduino.h> #include <Stepper.h> const int stepsPerRevolution = 200; // change this to fit the number of steps per revolution // for your motor // initialize the stepper library on pins 8 through 11: Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11); void setup() { // set the speed at 60 rpm: myStepper.setSpeed(60); // initialize the serial port: Serial.begin(9600); } void loop() { Serial.println("ONE MORE TIME!"); // step one revolution in the other direction: Serial.println("IN"); myStepper.step(stepsPerRevolution); delay(1000); // step one revolution in the other direction: Serial.println("OUT"); myStepper.step(-stepsPerRevolution); delay(1000); } |
I should have probably mentioned by now that there is an actual point of these weight lifting devices, as I mentioned in previous posts load-cells are generally ill-suited to continuous weighing, particularly in environments where the conditions don't like to stay the same. I am attempting to design a cost
