  • Wireless Remote Using 2.4 Ghz NRF24L01 : Simple Tutorial Using of NRF24L01 & Arduino

    Nice job I also am using these modules for a controller with a model here http://www.thingiverse.com/thing:1864536 I made a preliminary PCB for hooking up between the nrf module and arduino nano but am thinking I will modify it to just have the atmega 328p chip right on my PCB instead of stacking the modules.

    For troubleshooting use a voltmeter and check that wires are connected where you expect, also check the voltage on the 3.3V is going to the wireless module without a problem. Also can be useful to use Serial.begin(9600); in your setup and Seral.println("signs of life"); Serial.println(someImportantVar); in your loop function to see that things are working on the arduino side. The <p> is HTML syntax and is accidental (probably copy paste problem or issue with instructable formatting, would check the zip for code).Beyond the voltmeter I just bought and assembled a really cheap oscilloscope ($20-30) and even with this cheapo oscilloscope I can see some digital signals on various pins communicating to the rf module.Also read up here for more details https://arduino-info.wi...see more »For troubleshooting use a voltmeter and check that wires are connected where you expect, also check the voltage on the 3.3V is going to the wireless module without a problem.

The rf module will otherwise draw too much power occasionally causing it to "brown out".
