assalam o alaikum,
I am new to this forum, I am using a tx and rx and from that the servo motor is working but when i connect the signal wire and the ground wire from rx to the relay driver ckt it doesn't work from the tx and hence no output is received hence the ckt is working manually when i give 5v input from dc source it works properly... i have heard from my seniors to use uln2003(current buffer) in order to use the rx signal connection input to uln2003 and the output from the uln2003 to the relay ckt.
Have anyone around here knows how to use it?
REPLY ASAP
Regards
