Hello everyone, so I am new to arduino and looking for help designing a wireless launch control box. So I own the arduino Uno R4 WiFi and was looking to purchase another one and have them link wirelessly. I need the transmission end to have 2 switches for selecting which pad to fire and/or fire simultaneously with a launch button. The receiver end is the side I’m really running into issues, building a schematic for switching 5v-12v for the igniters. I can figure out a single launch option, but adding the second I am not able to figure out how to keep them separate without having 2 separate power supplies.
A cheaper, more compact and and much simpler option is to buy Adafruit Feather radio boards (example) which include an Arduino compatible processor and a radio on the same small board.
Code examples are provided that show you how to set up point to point communications right out of the box.
For the ignition, I would use a MOSFET switch.
For questions about wiring, please post a hand drawn picture of your proposed wiring (pencil and paper works great), with parts, pins and connections clearly labeled.
Keep in mond we can't see what you see. We need to see the code, any error messages and Serial outout, a photo of the hand drawn wiring diagram. Only then will your word salad begin to make some sense but there will likely still be many questions.
Okay, but first you should show us the schematic for your "single launch" option so we can understand better. Then we need you to describe your goal in more detail. Are you referring to how to power both boards (transmitter/controller and receiver/launcher), or simply how to send "commands" from the transmitter to the receiver via Wi-Fi, or something else?
Perfect, I will do that. Thank you for the help
Yeah suspected without a diagram it would be a mess. I will finish drawing it up and post it. Thank you!
