Use a latching relay. Here is one I found on Amazon. https://www.amazon.com/dp/B015MRQNXS/?coliid=I3LXTGKX4GEPUR&colid=31WWM91JAUE22&psc=1&ref_=lv_ov_lig_dp_it
If you are trying to use with existing 3 ways use https://www.amazon.com/dp/B015MSYQ8Q/?coliid=I3RP8X9OMYWU97&colid=31WWM91JAUE22&psc=1&ref_=lv_ov_lig_dp_it
Use an optocoupler to indicate lamp status...see the last diagram in this post. https://forum.arduino.cc/index.php?topic=435506.0
@sebdetours said in MDMSPanel "Nextion":
Did you take a standart case that you cut out?
Hi @sebdetours, yes. This is G1910 (Gainta) box. See drawing attached to projet files.
Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.
@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
