Re: Question regarding air quality sensor

Re: Stalker V3 powering on and off the SD card

Hi guys

Yes, it would cut off the power of SD Card while using digitalWrite(4,HIGH), and get power from battery after setting a low level to pin 4.

Try using the example sketch from Seeduino_GPRS_Master, named SIM800_Serial_Debug example. Then you could use AT commands directly and get response from Seeduino GPRS. This will help you to test a lot of parameters from your Seeduino GPRS and your Sim Card. To check your APN you could type: AT+CSTT...

By the way, did you put the library into a right path? Errors like that always occurred by a wrong path.

Re: Grove - FM Receiver

A few more questions . . . Can the FM receiver be used standalone, without any other boards (as long as it is connected to power)? And in this case, is it possible to tune the station directly on the board, or do I need to attach an external potentiometer? Will the board retain the previous station...

Re: Simple webserver with Wifi Shield

I have watched the video https://www.youtube.com/watch?v=ek63patAl80 And I can see that the code works, however, I think that there is some difficulty with the former boards; like I said before, I have the Wifi_Shield_V1.1 which is not the latest board. I have got a message : please make sure your ...
