Adafruit PWM PCA9685 Frequency Help

Using this as a base: https://learn.adafruit.com/adafruit-16-channel-servo-driver-with-raspberry-pi/library-reference I made code to control different servos using the PCA9685 board. However two boards need a frequency of 1000 hz and two boards need it to be 50 hz. When I try to change it to 50 hz l...

Re: Can I have this stepper motor lock in position?

How can I have two of these setup if rpi has only one uart interface? Also could I have a python code that tells it to stop or go and such?

Can I have this stepper motor lock in position?

I currently have a bi polar stepper motor (https://www.robotshop.com/en/12v-17a-667oz-in-nema-17-bipolar-stepper-motor.html) powering a lever. When there is a weight on the lever the shaft turns. I’m using a pwm controller (PCA9685) as an input to the stepper board (cytron SD02C) to get the motor to...

Re: How to control a python script over a local web server?

I really need it to work it lighttpd though, is there any way to simply have the usb device's event go straight through the browser to the server?

How to control a python script over a local web server?

The goal of my project is to make a robot that is wirelessly controlled. I can be controlled via a gamepad controller locally when connected to the raspberry pi (the raspberry pi is connected to a pwm board to which motors are connected). This is done in one python script and can do stuff for each b...

Controling Stepper motors using UART and cytron SD02C

Hello, (raspberry pi jessie) Trying to get a bipolar stepper motor running with the pi. I've already hooked up the board and tested the motor, which it works! Now I want to be able to control the motor. On the board it has UART outputs, and I was planning to connect these to the UART pins on the ras...

Using UV4l with uvc and mjpeg streamer help

The overall goal is to embed a camera feed into a website for a robot. So far it seems like the only things that work is uv4l-uvc webrtc. I can hit the call button and initiate the call and that works. However if I end it and try it again it sometimes does not work and I have to restart the pi to ge...

Help with a long wifi connection?

I'm using the pi for a search and rescue robot. I need the range to be around 100 meters. I was thinking about using a device like this: https://www.bhphotovideo.com/bnh/controller/home?A=details&O=&Q=&ap=y&c3api=1876%2C%7Bcreative%7D%2C%7Bkeyword%7D&gclid=EAIaIQobChMIg5LI18nL2AIVnYqzCh01wwaxEAQYDCA...
