Re: HC-11 433MHz wireless serial module (HCMODU0054)

I'm now moving on to the Pi which is a whole different story...I'm new to programming raspberry pis... I'm attempting to use the geany IDE and c++ wit...

Re: HC-11 433MHz wireless serial module (HCMODU0054)

Ok, great. I've ordered a few of these and the UART usb. Do you have any sample codes of how to use these on the Arduino or Pi to send and receive data? Or how I would set the channel and IO mode?

Thanks

Re: HC-11 433MHz wireless serial module (HCMODU0054)

Am I able to switch between sending and receiving mode on these modules whilst they are connected? And are they compatible with raspberry pi and arduino?

Thanks

Re: microSD card reader module - SDRamps (HCMODU0044)

How would I go about reading individual lines of the SD card of varying length? (From 9 to 12 characters) I'd imagine I can use a break variable when I save the data then use the Seek() to choose the line to read? But I'm not sure how to tell it to stop reading at the break variable. Or is there a r...

Re: SD Card Module (HCARDU0008)

Ok, I'll give one a try if you can confirm it will work with my set up.

Is this the correct module?

Re: SD Card Module (HCARDU0008)

I'm not seeing this with mine. I might not be catching it at the right point in the initiation but it continues to fail. Is the microSD reader any more reliable to use?

Re: SD Card Module (HCARDU0008)

I'm unable to get the reader to work on my arduino mega 2560. Below is my setup. The card never initializes. Ive tried using the 3.3 and the 5v supply pin and both grounds. The SD card is formatted to FAT32 by a windows 7 PC Tool MISO - 50 MOSI - 51 SCK - 52 CS - 53 And the code (from the arduino we...
