    Help talking to uart bus servos in 6 axis robotic arm

    So I am designing and building a 6 axis robotic arm and I really need help finding the right library and communication method to talk to the bus servos I have installed. This is the product page and this is the google drive with the documentation that the manufacturer provided. I also put an...

    Have servo move randomly without an IC

    Hi, I have a servo (Longrunner MicroServo 99 - Typ KY66) that I want to use to move a gun turret of my Millenium Falcon model. To make the movement look more realistic, I thought about having the servo and thus the gun turret move randomly left and right and also turn round instead of simply...

    Please help with Serial Bus Servos!

    Hi everyone, I'm confused how to connect and control these motors https://www.hiwonder.hk/products/hiwonder-lx-225-serial-bus-servo-25kg-high-torque-data-feedback Where do I find the pinout and where can I find some sample arduino code for controlling them? I think it said something about...

    Why Micro SD card can't log the data when we connect servo motor ?

    Hi guys, recently Iam making a project which includes Arduino Nano, MPU6050, BMP280, micro SD card module and a servo motor. Brief explanation of my project is basically I am trying to collect data from the MPU6050 and BMP280 and log that data with the help of a micro SD card module and the job...

    How would I go about creating a servo arm, controlled by arduino ?

    hiya! i am thinking of using an arduino nano and bluetooth to control a small car/robot. there will be a type of rake/filter on an arm at the end to sort litter. I want to be able to lift this arm (using servos?) and "shake" it to move the litter into a different compartment. How should I go...

    Soundboard and Servos (Jurassic Park Model)

    Hello! I recently built a scale model of the Jurassic Park Entrance gates but when I was getting ready to finally be done with it I had the thought I could add a servo or two in order to make the doors automatic. In researching this I decided, well, why don't I add a soundboard and some mini...

    Powering 10 servos from a single Li-Po

    I could use some perspective on a circuit I'm planning to build. It's a robot with 6 standard servomechanisms and 4 microservos. I'm set on using a single power source and three step-down converters to feed most of the servos + Arduino Uno + PWM driver with 5V but also supply 6V to two servos to...

    current measurement over time

    I have a RC servo towerPro sg90 connected to Arduino, to measure the current I have put 1 ohm shunt resistor between servo GND and power ground. Then I did a analogRead on the resistor, when servo sweep between 0 -180. I am getting following values out of my analogRead. So in total I have 180...

    HW Interface to detect Radio Control Receiver PWM signal

    I am using an Arduino Pro Mini to detect a PWM signal from a radio control receiver. The input pin on the Arduino is supposed to be limited to 20mA current with a max current of 40mA. I plan on using a 220 ohm resistor in the circuit. Do I need a .1uF cap to ground (and what kind of cap)...
