The setup worked well with a 100 uF capacitor linked to the NRF24L01PALNA chip on the Nano.Subsequently procured a large energy adapter as recommended by several to replace the capacitor.Expected to the lack of adequate 5V pins on the Nano, I attempted using one of the digital pins (arranged to OUTPUT HIGH) as the 5V insight for the HC-SR04 ultrasonic sensor.However, when I attempted to modify the sensor to various perspectives, the transmission became spotty and ultimately stopped.
Tried several troubleshooting ways but none of them proved helpful: Taken out ultrasonic sensor Checked for unfastened connections: attempted replacing cables Changed to a fresh breakout energy adaptor Removed adaptor and tried making use of 100 uF capacitor again Changed Nano with Uno Now, I am unsure if thé NRF24L01PALNA quests are inactive and I perform not possess any spare on hand for right now. Tried troubleshooting by calculating the voltage acróss all the hooks on the NRF24L01PALNA segments to their GND flag. Was thinking if beliefs can become likened to a working collection to notice if the segments are faulty. After calculating the voltages, the quests were after that changed out and measured again. Kindly advise if there are other methods that I can troubleshoot. Also, if the NRF chips are really inactive, what are usually the probable factors that might have got caused this (therefore I wont make the same mistake again) Give thanks to you. Give the nRF24 a distinct power resource - a set of AA alkaline tissue (3v) functions well and you would not really need the energy adapter. I have not used a single of thise strength adapters so I dont know what is its max insight voltage. Just create sure the GND of the distinct power supply is linked to the Arduino GND..R Simple nRF24L01 Tutorial. I only used the IO pin to power up the ultrasonic sensor, not really the nRF24. The ultrasonic detectors working current can be 15mA so it should not have destroyed the IO flag Furthermore I tried switching from the Nanó to a Unó and it nevertheless did not work. I also did test all the digital hooks with a easy Directed blink and they are all working. Will try out hooking up thé nRF24 to a independent power resource and observe if it works. Any idea how I can tell which module might become faulty centered on the voltages Does appear like one of them is certainly defective because despite working the exact same receiving program code, the CE voltage of Module 1 is definitely 0.02V while the additional will be 4.3V; while running the same transmitting program code, the CE voltage of Component 1 is usually 0.005V while the additional is certainly 4.5V. The low-power variations with PCB antenna will end up being good and are usually possibly cheaper..R.
