Hey all, I'm just becoming interested with 8 bit microcontrollers. I would like to build a few things with the absolute cheapest parts possible, like some Chinese LoRa modules, some PIC16LF1503-I/P mcu's, at only $1.50 each, I figure I can afford to play around a bit!
I would like to build some wireless devices that can activate a relay, to do things like open a solenoid to water the garden, turn lights etc...
I have zero idea where to start. How do you program these things? Do I need some kind of interface and development environment, like a USB device I can plug these chips into? And write the code too? What kind of code do most of them read, C? How many kb of memory and ram do I need to execute simple tasks like communicating through a LoRa module and turning on some kind of gpio pin to activate a relay?
Ideally I'm looking for the cheapest possible microcontrollers that can communicate over SPI, have atleast a pin or two that can be activated to control relays or camera's or other devices.
Thanks!
