Topic: Are components working (Read 277 times) previous topic - next topic


I am trying to build the Wireless weather station. Is there a way to find out the components that I have purchased work? The LEDs on the microcontrollers work but the ones on the DS3231 "RTC" and NRF24L01
"transceiver" they both are dead- no LEDs illuminate. Thanks !


Never seen an RTC with a LED.
Ditto NRF24.

What have you bought?

Yup, I have at least 20 RF24 radio modules from different vendors and none have an LED.  Here is a great tutorial for learning and testing the RF24 radios.


Thanks, that's what I was wondering. It looked like there might be LEDs on them but wasn't sure.
