    Help with creating a random routine for project

    First a quick background of my project. It's a remake of an "analog" laser spirograph I made a few years back. 4 small motors are setup with mirrors glued to the end. A laser is then reflected off each mirror. Varying the speed of each motor creates new designs. In this version the motors are...

    Variable pin assignment using PWMDUTY & 20M2

    I'm trying to write a program that takes inputs from 4 potentiometers, converts it to a PWM duty cycle and outputs it to one of 4 motors. The pot-motor is a static assignment, so say Pot1 directly controls Motor1. I'm early in the software design phase and trying to optimize my code since I know...

    PICAXE WS2811 RGB LED Controller

    So I broke down and bought a 5M roll of the individually addressable RGB LED strips based on the WS2811 current driver. I've been playing around with it on my Arduino using the Fast_SPI library (SPI_TM1809 chipset) and is relatively easy to write programs for. However, I can't really dedicate my...

    First L293D Motor Driver Project

    Sorry, I've been busy the last few days but I thought I'd post a final drawing with the caps added. I went back to terminals for Vin, but I forgot to label them. + is still along the top and - on the bottom.

    First L293D Motor Driver Project

    Okay, let's see how close I have it now. I made some changes to the schematic too: Cleaned up the design a little and straightened the traces. Added capacitors across the PICAXE Vin and motor pins. Added a battery instead of the terminal block for clarity and put the rails in the correct...

    First L293D Motor Driver Project

    I'm not exactly sure what you mean by "across motor pins." Do you mean between pins 3-6 and 11-14? I did some more looking around this morning and found this posted in Arduino's forum. The first picture shows a decoupling circuit from a motor run directly from supply/gnd. The 2nd shows it...

    First L293D Motor Driver Project

    I'm working on a project where I want to drive 2 DC motors, both programatically and with a with a pot, inputting to an 14M2 A/D. I've been doing some research on here and sounds like the L293D driver would work great. I'm still pretty new and I've never used an L293 before, so I'd like to know...

    Using a PICAXE chip to control multiple Ghetto Pixels (open source BlinkM)

    I recently decided to try out making my own Ghetto Pixels, they're an open source version of the BlinkM pixel. I've successfully made 10 ghetto pixels that I'm currently controlling with an Arduino and BlinkM's sequencing software through it's I2C bus as described in the ghetto pixel...
