Hi, i thought i would quickly give an update just to say ive cracked it, not really sure how i got the sound working but it is, i now have touch sensors that when touched play a sound via the audio jack and also triggers a relay. I still have a loud pop as the python script starts and stops but no p...

Hiya, i came across this post as i have four of these 8ch mechanical relay boards i am trying to control atm, i cant see that they are branded with sainsmart but i believe them to be exactly the same, im currently trying to figure out how to code them so that all channels are set high when a code st...

Aha, hello all on this post, i have 4 of these relay boards (as stock for various projects i would like to achieve) Ive made a board consisting of a 3v3 voltage reg circuit and a 5v0 voltage reg circuit, one MCP23017 and one MPR121 capacitive touch sensor, here is a photo https://www.dropbox.com/s/0...

Hiya Dave thank you for your reply, I know exactly what you are saying and I have gone back to the start, I know my touch sensors are working well every time channels 1-7 (not sure why the other 5 are not but 7 should be more than enough for now) I am stuck on the audio side of things, I have been p...

Hello and thankyou for taking the time to look at this topic, sorry but here comes an essay about everything ive done and want to do. I am struggling to understand and program with python to control my project. I have a Raspberry Pi Rev 2. I also have a board i have designed and made consisting of a...

somebody please help :-s I have designed and made a board consisting of an mcp20317 and an mpr121 with two voltage regulator circuits for my 3v3 and 5v0. I can see the mcp23017 and the mpr121 on i2c, i am trying to make a program very simular to the beetbox triggering audio with relay outputs for sw...
