What you are looking for is a mass flow sensor (MAF), or something along those lines as you mention wanting to know if there is flow, this gives you the 'speed' of the flow. There are various types av …

What you need to do is take an averaged reading, this is because the sensor is always fluctuating, noise on the 5V line or the signal line. There are possible hardware solutions. Adding a capacitor …

There is nothing wrong with your code. But it could use some cleaning to make it efficient. The code at the moment will be 'deaf' to any user inputs for twenty seconds between light changes. This c …

The beginning of your code in the loop: void loop() { digitalWrite(ledPin,LOW); //remove this line here if (digitalRead(switchPin)==HIGH) { digitalWrite(ledPin,HIGH);//DBG delay(500); …

An option would be to use a GPS module which would give you actual speed accurately, this data can be logged to EEPROM or SD and downloaded later or it can be sent wirelessly to a base station. Ther …

The is a standard with RC connectors, that is Black always goes to ground white/orange goes to the signal and red/brown goes to 5V. I don't know if you have made a typo, but you need to connect the …

The effect you are seeing is the result of floating pins. Because the inputs are not at any defined voltage level and will 'follow' the voltage applied. So leaving them unconnected with no defined st …
