NOT a coding issue - more of a config issue I'm gussing. I suspect I'm missing something in the setup of the Arduiono pins or a major ground/voltage setup This shouldn't be that hard to do!Īny clues as to where I've gone wrong would be of great help. When I re-connect the controller to pin 11 (Via connector blocks), it will go to 4.9v, but when Arduino goes LOW, the pin shows the 3.8 volts on the contoller! AFAIK all my grounds and voltages are common, and have checked for other wiring errors. Simulating Circuits with Fritzing JFritzing 0.9.10 released New parts: Sony’s Spresense Boards OctoFritzing 0.9.9 released. kids amateurs masters fritzmeisters Blog. Dehncombo, Spendi spandi effendi significato testo, Geliu pristatymas kaune nemokamai, Microstepping driver st-m5045, Id cards formats, 54974 weather. With the controller wire disconnected, my button presses show pin 11 going from HIGH (4.9v), to LOW (0v) as coded. Arduino bipolar stepper motor controller. When DIR- (DIR+ is VCC - 5V) on the contoller is tied to the Arduino, I can't get it to pull ground/LOW. The DIR pin is at around 3.8 volt and will cause the motor to reverse if I short it to ground. The diargram with the controller shows the control pins on it are going to an opto-isolator. I have pin 11 (PORTBP3) set as an input (default, no PinMode). Mostly working ok, stepping fine, but having a bit of a prob controlling the Direction pin on the driver box. I am controlling an ST-M5040 stepper motor driver with an Arduino Pro Mini.
