I have purchased a RioRand(TM) 433MHz Superheterodyne RF Link transmitter and receiver kits 3400 for ARM / MCU from
https://www.amazon.com/gp/product/B00HE ... UTF8&psc=1
The first thing i am trying to do is get the receiver to work
I have not been able to find an exact howto but found a bunch of related sites.
so what i have done ::
i went here https://www.princetronics.com/how-to-re ... -receiver/
installed wiringPi and 433Utils
i am using 3.3v to power the receiver from an article i found
https://forum.pimatic.org/topic/202/4-h ... ven-more/2 . where there is a section Homeduino on Raspberry Pi where it mentions
with all that i runHere’s one big difference to the Arduino wiring : the receiver will be connected to 3.3V!!
It is very important, since the Raspberry Pi can only handle 3.3V on the GPIO pins.
The Raspberry has a 5V out but when you connect the receiver’s VCC to 5V, the level of the data pin will be 5V too an this kills the GPIO of the Pi!
i point an RF device at it and nothing
so now i am at a loss.
would love any help or suggestions
