If I use a tactile switch to GOSUB forward, for instance.· How can I get it to remember the move?· Like, the direction and the distance. So that I could then use that info to run it in auto.
This is on a boe-bot.
Hi, you would need an encoder to keep track of the distance and a variable monitoring the switch to keep track of direction. You would then need a record and playback routine. During record you could write the direction and distance to EEPROM·then read EEPROM back during playback,Data direction byte,distance word,direction byte,distance word etc.
It is likely to begin with that movement/distance would only be in a forward direction so a sample data may look like "F",200,"L",0,"F",50,"R",0,"F",2000
I've tried this with out encoders and it can actually work quite well. forward was not just turning on the motors it was turning on the motors for 2 seconds. turning was done by turning on one motor for a specific amount of time. I tuned it in so 1 forward command would move the bot about 1' one turn command would turn the bot 45deg. if you've ever played with a big track it's similar to how it functions. for example F,F,F,F,R,R,F,F,F,F,R,R,F,F,F,F,R,R,F,F,F,F would make a 4' square. this works well if every thing is laid out in feet. Of course this is usually not the case so it does have it's issues. you could have make finer adjustments for better results. and I don't think you'll get near the accuracy of encoders.

Thanks for the response, Jeff. In my situation, it appears that a real encoder that attaches to the motor shaft wouldn't be feasible.... but I
could probably mount a homemade target to each drive wheel...
·Do you know where I could access some pbasic of examples of reading
a homemade encoder on each of two wheels?
Thanks,

Thanks a lot! Boy did you save me an awful lot of research and experimentation.

Have you looked at the BOE Bot Digital Encoder Kit?
