This is a first time build for me, for a project that basically delivers smells using ceramic resistors as heaters and fans for flow.
There are 20 heaters and 19 fans in total.
I have tried to build a schematic in multisim but have run into a major problem (please see attachment for jpg and multisim file):
I have been told that using a PIC10 alone will not be sufficient to switch on the MIC's due to its lack of inputs but can be compatible with in circuit programming.
I have been recommended to use a PIC12 to have a dedicated program pins
Can someone suggest me an appropriate PIC12 and the way to wire it all up with the CA-42 and MIC's?
Few other things:
1. Are the pin configurations correct?
2. Unsure on which connections to use from the USB - serial Cable (CA-42)
[I think the Sin and Txd are wrong] can someone explain which pins do what.
3. Do i leave serial out pin on the last MIC?
