I am still using several temp/hum sensor and they are running great I also have just added code and pictures for my newly build light sensor (using an LDR).
@Olaf-Jacobs It's a straight analogue read on a single ADC pin relative to Vcc and ground of the Arduino Node.
In my case it's a pro-mini, the ADC pin in this example earlier defined as "Pressure", the result radioed in only if the ADC reading has changed. Three other binary inputs for contactors are polled every second on separate digital pins (one of which is pin 3), which uses all 4 pins available on this pro-mini due to the radio etc.
if ((!hidro&&!Hidro&&(counter2>=132))||initialise){
int incoming=analogRead(Pressure);
if (prevolume!=incoming){
prevolume=incoming;
sleep(50);
float tankvolume=(((incoming-102.3)*6.704199635)+0.5);//5psi sensor
send(msg8.set(tankvolume,0));//This is actual volume
sleep(100);
}}
I'm not clear on the rest of what you're trying to incorporate or what pin 3 (digital interrupt) has to do with it, the pressure sensor signal goes to an analogue pin to enable the voltage to be read.
Hi!
Going through examples and forum topics I've noticed that I'm using the wrong S-type and V-type.
I'm writing a new version of the code with S_LIGHT and V_LIGHT so there is now dimmer functionality (which I don't need).
Let's see if this helps.
@Sunseeker According to the Connecting the Radio page, D2 is the default pin for the CE signal for the NRF24. If you'd like to use this pin for I2C, you can free it up by assigning a different pin for the CE signal by adding this line to your sketch:
#define MY_RF24_CE_PIN pin
IIRC, all available pins should work for this purpose (D0, D3, D4). Just pick one and if it doesn't work, use one of the other pins. Please make sure to add that line before #include <MySensors.h>.
@Nca78 said in Dimmable LED kitchen light (Arduino, APDS-9960, RGBWW led):
Do you use a relay to control the leds or still a MOSFET ?
i'm using mosfets.
