[ sorry for poor English ]
I'm doing my rf remote project with Arduino nano and nrf24l01,,, i have a trouble with it... When i press any one button on the transmitter side, it working fine,
( The output voltage of particular pin gives 4.8volt (say 5volt))
But press more than one button (2 or 3 etc), the voltage droped at the receiving end pins
What that error, and how to solve this problem...
Results:
Condition 1: [ok]
Switch Pin 1 - Press
Relay Pin 1's output - 4.8volt
Relay pin 2's output - 0 volt
Relay pin 3's output - 0 volt
Switch Pin 2 - Press
Relay Pin 1's output - 0volt
Relay pin 2's output - 4.8 volt
Relay pin 3's output - 0 vol
Switch Pin 3 - Press
Relay Pin 1's output - 0volt
Relay pin 2's output - 0 volt
Relay pin 3's output - 4.8 volt
Condition 2:
Switch Pin 1 and switch Pin 2 press at same time,
Relay pin 1's output - 2.4 volt
Relay pin 2's output - 2.4 volt
Relay pin 3's output - 0 volt
Condition 3:
Switch Pin 1 and switch Pin 2 press and Switch Pin 3 at same time,
Relay Pin 1's output - 1.2volt
Relay pin 2's output - 1.2 volt
Relay pin 3's output - 1.2volt
