Arduino nano 5v and 3.3v nRF24L01+ transceptors

-

hi everyone,

i'm having trouble arduino nano bought in ebay sometime ago. want use nrf24l01+ transceptor, according specifications accepts 3.3v on power pin (but 5v tolerated in data pins). seems arduino nano has 3.3v port, multimeter indicated 5v  :o . followed instructions , using resistors made voltage divider , got 3.3v.

the thing is, transceptor works if connect 5v pin, not "new" 3.3v pin created, , i'm afraid damaging radio. works minutes , stops responding , must reset (but maybe it's unrelated).

why not working using 3.3v input?

btw, i'm using of these transceptors in battery powered 3v3 arduino pro mini, , seems work (with random crashes after hours still have figure out...).

hi,
a resistive voltage divider not work when load (the nrf24l01) has current changes lot.

see page  here:

the "base module" shown there solution providing 3.3v 5.0v , has bypass capacitors...

First use of Arduino Uno : avrdude error on Blink uploading

-
hi all, i bought arduino (or should genuino) starter kit. first test , failing. i have follow religiously first pages , when trying upload blink sketch, uploading fails avrdude error : avrdude: stk500_recv(): programmer not responding. as suggested in other posts, have tried 1) switch latest hourly build of arduino ide 2) switch previous stable version of arduino ide (1.6.09) 3) change usb cable 1 know working fine 4) make same steps on computer (unfortunatelly, of them macos running on macos 10.11.6, not interesting test) 5) press reset before upload, interesting thing : tx led never flashes the full log attached. idea of why happening ? to save people having download log, it's sync error, resp=0x00 every time: code: [select] avrdude: stk500_recv(): programmer not responding avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00 avrdude: stk500_recv(): programmer not responding and he's running 1.6.11 hourly avrdude 6.0.1. ...

salve, prima di installare joomla, vorrei porvi tre semplici domande: 1) l'ultima versione in italiano di joomla, supporta questo template prodotto da gavik? loro scrivono che non è un semplice template, ma una vera e propria suite, ma vorrei una vostra opinione. qui sono descritte le funzioni della suite. 2) per sfruttare gli elementi che si vedono nella pagina, ad esempio quello in alto sinistra dove scorrono le notizie, occorre installare qualche componente aggiuntivo? 3) futuri upgrade alla piattaforma joomla, potranno inficiare il funzionamento o la compatibilità del template? vi ringrazio anticipatamente della disponibilità. 1) non vedo nulla di particolare se non una miriade di posizioni per blocchi 2) è un modulo se non sbaglio pagamento, ma adesso non ricordo bene 3) no. ti ricordo che devi installare joomla  1.0.12 Board index Joomla!
