i have to make a weather station for my hnc electronics course. i have a utft touchscreen and mega. i can get a menu screen for the touch screen display, i want to use a dht22, bmp108 and ldr sensors. i want to send this information to the computer through the nrf24lo1 and display it somehow on the computer screen. the utft will be a portable display with sensors attached.
i have connected up and loaded the getting started sketch, one nrf24 says “got payload…sent response” or something to that effect. the other nrf24 is saying “failed response timed out”
i did manage to get a few bits of information through, apparently it is supposed to show the time. i didnt get this. i only got a confirmation and delay time of approx 30 seconds.
i have heard that the supply for this isnt that great, i mean taking a supply from the arduino 3.3v isnt that great. and some people solder a capacitor onto the nrf24 supply and ground as a way of smoothing out a rough supply. is it this rough supply that is causing problems?
