Having trouble getting my new Nexus Robot Arduino 328 Microcontroller to be recognized by the Arduino IDE. What name should it have in the Board Manager list? Also, the power LED when connected to the computer via USB is red.
It is more than likely based on the Duemilanove design which uses a 328 chip and an FTDI for USB to serial.
That was it. Thank you very much again!
The attached photos show my setup to control (2) 12V DC motors with an Arduino 328 Microcontroller and joystick. The joystick x & y leads are in Analog pins 0 and 1. What program do I use to simply make this joystick control the dual outputs? Simple for you if you’ve done it, but I haven’t the slightest clue. Is this setup even correct?
It’s a learning process. You will need to understand the code used to drive the motors, then understand analog input, and merge the two.
We are not aware of any specific sample code, but you can still try a search online for L298P + Arduino + Joystick + Code
I appreciate that advice and patience, but I can’t find anything online for the L298P except for an unanswered question on Arduino’s forum. forum.arduino.cc/index.php?topic=312819.0
I’ve spoken to local “experts” about it and they all give me the same answer you have. “Make the analog joystick work” (which I have accomplished), “make the motors work” (which I cannot accomplish), then put the two together.
My problem is that I can’t find any info about this motor controller to make the motors work. There is no online tutorials on this board. Everything online uses Arduino Uno’s, breadboards, and H-bridges like this one: tronixstuff.com/2014/11/25/tutor … d-arduino/
I need instruction for your product: robotshop.com/en/nexus-robot … oller.html
The schematic diagram, robotshop.com/media/files/pd … c_v1.3.pdf, doesn’t do me much good. I am really at my wits end about it. A simple 2-minute video for this board by someone sure would help.
Try some standard code. Note that there are jumpers next to the screw terminals for E1, E2, M1 and M2 which need to be in place.
This is a “full speed” test which should ideally have the motors rotate at full speed. If they don’t rotate in the same direction, cut power and switch the wires to one motor.
/* Copy and paste the code below into the Arduino software */
int E1 = 6; //M1 Speed Control
int E2 = 5; //M2 Speed Control
int M1 = 4; //M1 Direction Control
int M2 = 7; //M2 Direction Control
void setup()
{
int i;
for(i=5;i<=8;i++)
pinMode(i, OUTPUT);
Serial.begin(9600);
}
void loop()
{
int leftspeed = 255; //255 is maximum speed
int rightspeed = 255;
analogWrite (E1,255);
digitalWrite(M1,LOW);
analogWrite (E2,255);
digitalWrite(M2,LOW);
delay(100);
}
