Sensitibity problem

Hello, I have a problem with my Tricopter, i hope than you can help me. I'm using WM+ (original) + NK (original) + BMP085 + HMC5883 I have tried with version 1.9 and version 2.0. My tricopter flies very well if i have carefully. I have been able to fly it during all the battery (ten minutes) without...

Re: Attemp to integrate sonar (ultrasonic sensor)

I use an Arduino ONE that has an output of 3.3V. I think the Arduino Pro Mini (5V version) also has an output of 3.3V that can be used instead of pin 12.

If you do not have that output you will have to use a LM117 to pass the 5V to 3.3V, as illustrated in the diagrams.

Re: Attemp to integrate sonar (ultrasonic sensor)

Hi All, I think Vallekano's code do not work in my board(Arduino Nano) as it miss one "pinMode(HCSR04_EchoPin, INPUT);" command. And I've merged Vallekano's code and mahowik's code together, so: 1. It still use D8 for TX pin, and D12 for RX pin 2. alt-hold data based on sonar data in rang...

Hello, Many connection diagrams are prepared to monitor the battery: m As I see it, join the positive and negative battery with a resistor, and from these to pin A1.

Re: Attemp to integrate sonar (ultrasonic sensor)

I use D8 and D12 Thank you for getting the HC-SR04 working! I think I'm being a bit thick today, plus this is my first arduino project so I'm still learning. My question is, what pins are you using off the HC-SR04? I see a Vcc, Trig, Echo, and GND. How do those correspond to pins D8 and D12 on the ...

if yes , than i will test your code :D


I think it would work well, but in the code instead of dividing by 58, I think you'd have to divide by 118.

The problem is that Baro give us a absolute altitude (sea level) and de sonar give us a relative altitude (ground).

Re: Attemp to integrate sonar (ultrasonic sensor)

I managed to operate the HC-SR04 Ultrasonic Sonar, without use of any auxiliary device. I integrate it into the MultiWii 1.9 code. To make it work we need to use the D8 and D12 ports so we can not use AUX2. Here is a sample image. The measured distance is seen in "debug3" and is measured i...
