Main Examples Download instructions here. 4dc.py This is a simple terminal script for providing user toggling of the 4 drives. It uses the rpi.gpio library for commanding the GPIO pins and a simple interface which allows you to type which drives to toggle, allowing you to toggle more than one at the same time. stepper.py Another terminal script, this time controlling a 6 wire stepper motor, connected as explained on the specification page.

Installation issues Permission denied, file not found, 404 or similar: There are a few possible causes of this: Out of disk space: We have occasionally seen this with people who have smaller SD cards, check by using df If the Use% column reads 99 or 100% on rootfs you probably need to remove some files to free up space Unable to find file / 404: Most likely the...

Main examples Please note that this installation expects you to be connected to the internet, it will download RPi.GPIO and WiringPi for using GPIO from Python. mkdir ~/picoborg cd ~/picoborg wget http://www.piborg.org/downloads/picoborg/examples.zip unzip examples.zip chmod +x install.sh ./install.sh Manual download: https://www.piborg.org/downloads/picoborg/examples.zip At the end of the install a desktop icon will appear for the example GUI, you should now be ready to go. General usage Please note that without any code running...

With PicoBorg, you can turn on and off fans, motors, solenoids, relays etc. from your Raspberry Pi. There are 4 low side drivers so you can turn on and off 4 devices One is connected to the RPi PWM pin, so you can vary duty cycle (normally vary speed). Update PicoBorg now comes with a 2A fuse and pull down resistors. Example uses 4 fans on/off control over all...

Nobody likes it when computers overheat, especially when you venture into the realms of over-clocking! So we thought it would be great if you could setup a fan for a Raspberry Pi to work the same way they do in a laptop, turning on when it gets too hot and turning off again when it is sufficiently cooled. We have a drive control board, PicoBorg, which should be plenty...

We controlled our PicoBorg from a remote keyboard control previously using RemoteKeyBorg, but what about using a joystick or gamepad instead? Well it seems like a good idea to us, so we thought we would make an example to get you going. This example will work with either a wired or wireless joystick, as long as the Raspberry Pi can see the joystick properly. Connecting...

Want to be able to control your PicoBorg from another Raspberry Pi or computer, then you want RemoteKeyBorg! RemoteKeyBorg is a pair of scripts that allow a Raspberry Pi with a PicoBorg to expose itself on the network and another to command it. This example is intended to demonstrate using the keyboard left, up, and right keys to control a three wheel robot :)

Everybody likes technology, even pets do! We thought it would be great if you could setup a Raspberry Pi to feed a pet at certain times of day, and a controlled amount. Thanks to Tristan Linnell for the idea :) We will use a PicoBorg to control a 6 wire stepper motor, which when driven will rotate a fixed amount for each step (the angle is specific to...
