13 - Output Devices: Hello RGB, Stepper & LED Array

Hello RGB

Hello Stepper

Hello RGB

UPDATE: I had a bad jumper wire (the connector was comming apart on the inside). Motor runs now.

The stepper board is not yet working. I am currently working on adjusting / testing the following:

  • Wires are wired in the wrong order -- try swapping them
  • Step pulses are too short for the motor -- try making them longer
  • Step current is too low for the motor -- try increasing PWM current
  • Not all MOSFETs working -- try probing with scope

To Flash the Microntroller:

To program your Hello LED Array - download all the files

I am using a attiny84:

sudo make -f hello.array.84.make program-usbtiny
If you are using a attiny44 run this code instead: 
sudo make -f hello.array.84.make program-usbtiny

If Working - This is the Terminal Output Produced

avr-objcopy -j .text -O ihex hello.array.84.out hello.array.84.c.hex;\
avr-size --mcu=attiny84 --format=avr hello.array.84.out
