Looks cool! Do you have experience with capacities switches? I did not play much with them. afraid to use close to AC interference though...
You need to use a capacitive IC with active shielding, basically you have an extra electrode around your touch electrode and the touch IC will compare capacitive change of the touch electrode with capacitive change from the shield electrode. If the change is due to electrical interference then both electrodes will be changed in a similar way and the IC will not trigger.
@gohan said in Arduino Pro Mini Shield for RFM69(H)W:
If I remeber right that pin is used as input so the RFM69 is not receiving any 5v signal. In addition there are people claming they have the RFM69 module working on 5v on data pins and 3.3v on vcc, but I hardly suggest to do it.
thank you just what i thought .
about direct 5v on data...well... i seen a big red sign saying n :DONT do it! lol
Level converters are so cheap...that i ordered 5 or 10 thoguether with rfm69 board.
sorry about hijack this topic, i though i was on general discussion
Does anybody have a link to a fixed version of this board? It's exactly what I am looking for form-wise, but I'd be nice if VCC was wired to 3.3v out of the box. Thanks!!
Not yet !
In fact, the interrupt must be short enough and fast enough to be sure to not miss the RFM69 interrupts.
The code for 8 dimmers will not be really more complicated : in fact, each time we got a zero cross, we must set a timer to zero, and then wait the good amount of milliseconds to turn on the needed outputs.
So, yes, we'll have an interrupts each 10ms (each time the wave crosses the zero, to be precise !), but I think all we have to do in the interrupt handler is set the timer to zero (or to micros() ...) and then on the main loop, wait the good amount of time for each output before setting them ON.
Seems simple on paper, perhaps it will not work on the chip....
In facts, my main concern is : will the RFM interrupt be short enough to not disturb the zero crossing interrupt ?
Although, not yet tested the RFM : do we NEED the interrupt pin ? Can't we poll frequently the RFM?
@KevinT
yes in general subghz radios have better range than 2.4ghz.
I might have farther nodes but for example, I have one rfm69cw at 55m from the GW and it's ok, with many obstacles on the path (7x rock walls, a part of the roof is metallic, metallic doors etc).
This depends on many factors of course
