I'm having a weird issue with the L298 and the Movement Panel in ARC.
I connected the L298 as explained in the tutorial section. With these exceptions:
I used jumpers instead of solder for most of the connections. D0, D1, D2, and D3 for the left and right triggers. D4 as the PWM (in my original set up, I used D8 in the video)
When I used the Movement panel, the motors did not seem to respond. While trying to diagnose the issue, I switched the ports for the triggers and accidentally chose the PWM port for one of the trigger ports. This activated one of the motors.
Subsequent tests proved that this port would activate one or more motors, but only in one or two directions.
The video below may explain the issue better. I'm thinking the L298 is defective, but I wanted to run this by the group first in case I just wired something incorrectly or my ARC set up is wrong. Thanks for looking. :D
Ahh, I think I can help. Set it all up the first way you show and make sure you move the slider on the PWM panel up to at least 25%. Now give it try. if the wheels start spinning you can move the slider up and down and see the speed increase and decrease. You need to have the PWM enabled to get the wheels to spin.
Go, Go, Gadget-Wheels!
Wow. I knew it was going to be something simple. I switched the PWM as you suggested and the motors came alive! Thanks, so much for the quick response!
Glad that I could help. That one gets me now and then when I set up a motor controller. Your video helped me to see what was happening (or not happening).
Have fun!
I just keep thinking how that video is about 4mins 26 seconds too long...and the two hours of my life I won't get back because I forgot what the word "Off" means. eyeroll
