How to connect spec to two motors and battery

The above is the connection from motor to sabertooth.
For connection from microcontroller to sabertooth.
With reference to this quick start guide http://www.dimensionengineering.com/datasheets/Sabertooth2X25QuickStart.pdf
There are 4 signal pin S1,S2,GND,5V
S1,S2 is the signal pin to control the two motors.
Select analog 1 mode.
An analog voltage of 2.5V corresponds to no movement. Signals above 2.5V will command a forward motion and signals below 2.5V will command a backwards motion.
Connect the pwm pin 9 and 10 from the arduino to S1 and S2 through a RC filter circuit
Connect the pwm pin 9 and 10 from the arduino to S1 and S2 through a RC filter circuit
Or to make it simple, simply testout your sabertooth with potentialmetre connected to S1 and S2 to test out
Wire up everything and test out the code, use some weight(coca cola bottle is a good example) to test first before trying to hop on it the first time. You might want to connect up a deadman switch to cut off the supply when it goes wrong.
thats ADXL 203 no found anywere and no can buy anywere,only have ADXL 193

How change all code working other thats sensors ????
now i found similar IMU board and have idg650/mpy6050 gyro/avcceletometer board, and dfrobotic l298p motor driver board(little test robot first)
ReplyDeletebut i no understand how i drive motors different motordrive board. sabertooth use only serial in put S1 and S2 but all little robotic ardunio shield have l298p driver and neer 2 pwm(both motors) and 2 DIR input forwar or reserve.left/right and stop. how change code sabertooth out and l298 driver in ?????
if anybody can help how change code.
send code help to me mail. about matii43 and yahoo plus com.
i need test thats segway first little robot. interesting lot, many month read and looking and orden parts.
