As the analog pins share a single A2D, rapid use of it can cause the previous read to impact the next. A common workaround in this situation is to read twice on each input, ignoring the first. try that: // read analog pin (void) analogRead(BATTERY_SENSE_PIN); int sensorValue = analogRead(BATTERY_SENSE_PIN); // calculate battery voltage float vBat = static_cast<float>(sensorValue * (V_MAX/1023));

Hi to @Greymarvel .Well i already seen this movie before. I bought diferent nrf24 nodes,amplifed ,not amplified,with or without capacitors. In fact i had worst redults with amp nodes. I just change to rfm69hw and w . No more low power/high power...etc. now i got my 4000m2 terrain covered (around 80m long). I didn't check max range but i never had lost a packet again. I was a very good increment on my network stability. That fake nrf24 chips are crazy and unstable and yes,all ebay cheap nodes are fake second i know.

Have a look at youtube and look for Paul McWhorter. He has 25 excellent newbie Arduine lessons.

yes, it requires the ip of the device running the ethernet gateway
