Hi, I have a Doppler radar which I want to get going on my Arduino mega.
I have attached a datasheet that I think is it. WB-010 ( bought off ebay for $4, seller couldn’t provide any info ).
First off, it says its max current is 60ma. Is this fine to run off the Arduino 5v line?
I also have an LCD, its backlight, and two 74hc595’s running off 2 different 5v connections. Are these going to affect the amount of max current my third 5v pin can provide to the radar?
And finally, the data sheet says the output signal is 100uv min to 250uv max. Would a 2n3904 be usable as an amplifier or even two in a darlington configuration. ( I also have 2n3906 if they are of any use ).
If anyone else has had fun with a radar like this, let me know what you did with it.
cheers in advance.
