Can somebody help me with a 315Mhz RF module? Answered
At the moment I'm building a circuit that should make a little motor turn forwards or backwards. It will be controlled by an 315Mhz RF module, wich i've bought from dx.com.
The circuit contains: a voltage regulator, a H-bridge for the motor, and a reveiver.
When i connected the circuit on a breadboard everything worked perfectly (even without an antenna connected I could control the motor over 20 meters away).
Then I soldered everything in place, connected a 23,8cm antenna to the board and I placed the hole thing in a plastic container. Then the trouble came. I can only control the motor from 50 centimeters away, if i go futther the signal light will blink instead of a continuous light. Can anyone help me out?
