Hello,
Hey I got this RF transmitter and receiver pair from ebay (Says 434Mhz and ASK modulation)
http://www.ebay.in/itm/280952855034...:IT&_trksid=p3984.m1439.l2649#ht_1883wt_1139
Its same as
https://www.sparkfun.com/products/8950
I prepared a test circuit on a Breadboard/project board as shown in the Attached Image
on turning on the power the Data Pin on the receiver side Always remains HIGH (+5v) no matter what
Even when the transmitter is removed from the circuit the receiver give HIGH output at data pin
I'm using the digital data pin and the ground pin to form the data out circuit as you can see in the figure labeld as data terminals
However a the data pin on receiver goes to LOW state for a split second whenever i give a +5v to the data pin of the transmitter i.e closing the D switch (this may be due to the fact that I'm using the same power Source for both transmitter & Receiver) after then it quickly becomes HIGH again
there is no tuning controls available on the pair either
What am i doing wrong? has the ASK modulation has to do something?
Please help me
