So i have 2 3v motors using a adafruit motor shield... The problem that im having is that if i run specific code it doesnt work (examples underneath)
So i tried with a single 9v powering everything, also installed 0.1 caps on the motors, tried with a 2, 3 and a 4 cell AA holder and no go.. When i tried to do a delay, or a forward follow by something else and upload the code everything freaks out it doesnt start, it tries but it doesnt
like if i use this code:
motor1.run(FORWARD); // turn it on going forward
motor2.run(FORWARD); // turn it on going forward
or
motor1.run(BACKWARD); // turn it on going backward
motor2.run(BACKWARD); // turn it on going backward
it works fine
or if i use this:
motor1.run(FORWARD); // turn it on going forward
motor2.run(BACKWARD); // turn it on going backward
it works fine..
if i use this:
motor1.run(FORWARD); // turn it on going forward
motor2.run(BACKWARD); // turn it on going backward
delay(2000);
it freaks out tries to start but it doesnt, then it tries again and fails..
also tried this:
motor1.run(FORWARD); // turn it on going forward
motor2.run(FORWARD); // turn it on going forward
delay(2000);
motor1.run(RELEASE);
motor2.run(RELEASE);
i mean when i use the delay function the motors dont even start.. i mean you can hear them trying to start but they dont... so not sure whats going on..
tried putting another 3v motor outside of the gearbox with code that didnt work and it works fine puted the same cables to the 3v motor inside the gear box and no go.... not sure whats going on...
I sounds like your batteries are not able to deliver enough current to get the motors running when they are under load.
Try with a powersupply that can put out more current.
When a DC motor starts up, for a short while it can draw a lot more current than when it'srunning. Also a free running DC motor draws less current than a moter that "is doing work" like driving your gearbox.
#include <AFMotor.h>
AF_DCMotor motor(2, MOTOR12_64KHZ); // create motor #2, 64KHz pwm
void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps
Serial.println("Motor test!");
motor.setSpeed(200); // set the speed to 200/255
}
void loop() {
Serial.print("tick");
motor.run(FORWARD); // turn it on going forward
delay(1000);
Serial.print("tock");
motor.run(BACKWARD); // the other way
delay(1000);
Serial.print("tack");
motor.run(RELEASE); // stopped
delay(1000);
}
when i run that code, the wheel starts spinning forward for 2 seconds, it then stop for half of second and start spinning forward for 1 second, then it spins backward for half of second then stops for 1 second. then it tries to start and stop within 1 second, then it runs forward for 5 seconds...
No idea what is doing :S
It should run forward for 1 second, then back for 1 second, stop for 1 second and then repeat... Is not doing this at all
but at that same code i comment everything but the part to go forward and and delays it works just fine
and if i do this:
#include <AFMotor.h>
AF_DCMotor motor(1, MOTOR12_64KHZ); // create motor #2, 64KHz pwm
void setup() {
Serial.begin(9600); // set up Serial library at 9600 bps
Serial.println("Motor test!");
motor.setSpeed(200); // set the speed to 200/255
}
void loop() {
Serial.print("tick");
motor.run(FORWARD); // turn it on going forward
delay(3000);
Serial.print("tock");
motor.run(BACKWARD); // the other way
delay(3000);
Serial.print("tack");
motor.run(RELEASE); // stopped
delay(3000);
}
It runs backwards 6 seconds, then stops for half of second runs forward for 1 second stops for half of second then 6 seconds backwards
