Hi, this is my first experience with SparkFun and I have never used some of the devices I have bought for this project. I’ve purchased three Arduino ProMinis, three transceivers, three small lipo batteries, as well as a vibration motor. I am confident that my three systems are wired correctly and the soldering job is up to par. I was trying to test whether or not they would send and receive signals. I used the default code and tried to get the system that was plugged into my computer to send a signal to my second device telling it to blink its LED, and I still was not able to get the LED to blink.
Hello, and thanks for your post.
What transceivers are you using and what tutorial are you following? Can you send links to the tutorial and photos showing how everything is connected?
I am using an RFM69HCW Wireless Transceiver - 915MHz, and am using the code from the SFE_RFM69HCW_example page
The best I can tell, you have the correct pins in the right places. I’m not sure why it’s not working for you. Did you use a 5 volt FTDI or a 3.3 volt FTDI when you programmed your boards? The only difference I can tell with your setup from the tutorial is that you don’t have a 10uF and 0.1uF cap across the power supply pins for the RFM69. That could be the issue or it could be something else. You might try adding some caps and see if that helps.
Thank you so much, I used a 3.3 volt FTDI to download everything, I’ll try adding some caps and see if that fixes the problem, thank you so much
Where would I connect a capacitor if I am trying to avoid using a bread board?
Both caps need to go across the power pins for the RFM69.
