Cheap remote control on Netduino

06 October 2011 - 08:51 AM

Hey there,

it's some time gone since my last visit. But I finished building my RepRap 3D printer (sry in German)

and now I want to create a little robot with netduino

Are there any tutorials on how to use and implement a remote control in a cheap way?

What do you suggest? I read about using the PS3 Controller with a bluetooth dongle? Or do I better use the standard 2.4Ghz remote control? Where can I get cheap controls and receiver?

Hope this are not to much questions. But it would be nice if any of you got experience in this and can help me

Best regards,
Freeman

control dc motor with dual motor driver

23 August 2011 - 09:31 PM

Hello, it's me again

This time I tried to control an dc motor with an TB6612FNG dual motor driver.

I am not sure if I connected the motor in the right way. Maybe one of you could check that.

List of connections:
- OutputPort (true) on AIn1
- OutputPort (true) on AIn2
- PWM (setdutycicle = 100) on PWMA
- OutputPort (true) on STBY
- 5V on VCC (or VIn of Netduino)
- GND on GND

- Motor 5V on AO1
- Motor GND on A02

It seems that there is anything wrong. If I connect my VIn from my battery pack with VCC the chip of the motor driver gets very hot

Would be nice if any of you could help me

[Netduino] How to use radio remote control?

20 August 2011 - 05:38 PM

Hey there, is there any tutorial to connect a receiver of an radio remote control to an netduino? Or is there any breakout board to get the input? My plan was to buy a simple 4 channel 2.4Ghz sender and receiver and connect them to my board. It would be nice if I only need one pin per channel and get values between -100 and 100. Hope you can help me

control brushless motor (+ controller) with pwm

19 August 2011 - 04:18 PM

Hello,

I am new to that hole electronic world and at the moment I am trying to control a brushless motor with my netduino.
The controller has a kind of handshake:

full speed (needs at least 1.5ms duration)
connect akku
zero speed
{*]beep beep beep!
ready

so i use the following code, but it did not seem to work, I already tried other ways, but nothing seems to work

PWM Servo1 = new PWM(Pins.GPIO_PIN_D5);
Servo1.SetDutyCycle(1);
Servo1.SetPulse(20000, 1800);
Thread.Sleep(300);

while (true)
{
    Servo1.SetDutyCycle(1);
    Servo1.SetPulse(20000, 1500);
    Thread.Sleep(300);
}

it would be nice if any of you could help me
