Hi there,
First of all I would like to say, that I'm a beginner in electronics, I watch the eevblog on youtube every single week, for quite a while.
I built a pretty basic schematic myself, and not surprisingly it works but not as expected since I built it myself. lol
I'm using a pair of RX-TX 433mhz modules, for a IR remote extender. It works, it transmit data and the receiver just repeat the data transmitted. The problem, whenever the transmitter is not sending any data, the receiver part keeps picking noise.
This part works just fine
RX module keeps receiving noise.
I tried adding 10k and 4.7k pull-down resistor to the data-out pin, without any success. mesuring with a multimeter there's a voltage floating around 1.8~2.8volts.
But the datasheet says
Data High | +200uA | Typical Vcc
Data Low | -10uA | Max 0.3v
I need help.
