I have setup this EM4095 with my arduino and everytime I run an oscilloscope on it for some odd reason it transmits at 60 khz when it is supposed to be 125 khz. The circuit i use is below and for the antenna I made a loop antenna at 450 uH. Anyone know what the problem may be?
I moved your topic to an appropriate forum category @watchittoughguy.
In the future, when creating a topic please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
How are you powering it? Post a link to the source.
I am powering it with 5 volts pin from arduino uno
Yes. Your scope probes are shorting the antenna circuit. You gave no clue where you placed the probe and the probe ground connection.
The LC circuit with the 450uH coil and the two 1n8 caps (3n6) should indeed resonate at about 125kHz. Unless the parts values are not what you think they are.
Show us more (images).
The 60pF capacitance of a scope probe can indeed de-tune the coil, but not significantly.
C7,8,9 are critical.
