GND on breadboard is provided by Arduino. The RF module uses this GND, as do the unused logic-analyzer channels. Every other probe, connected to the Arduino digital output pins, are staggered and separated by 1 row each on the breadboard to reduce any chances of crosstalk. Is there something else I could check ? | |
