    I am trying to make an arduino project that has 2 temperature sensors connected to two different LED strips(WS2812B). I want the lights to change depending on the temperature of each person. Colors would be blue for cold, orange for normal, and red for hot. I would like the motion on the lights to be a color wipe. I would also like to connect two small motors to rotate objects with a motion sensor.

    I need help in implementing a use case with LoRa SX1278 operating at 433MHz. I want to send a signal to another LoRa/RF receiver when an even happens WITHOUT using any microcontroller/Arduino. For the event, there is already a sensor which works like a relay - normally open, normally close and neutral. I want to send a signal, whenever neutral gets connected to NO or NC. The receiver can be LoRa but I would prefer a normal 433 MHz receiver. No specific message text is required for communication, only the receiver should be able to differentiate with two type of singal for NO and NC.

    We need a 24vdc in to 7vdc out - buck converter @ approximately 1.5amp to power an Arduino Mega / DUE. The onboard regulator gets hot if driven above 8vdc, so I want to have a dedicated 7vdc PSU that doesn't get hot like a traditional linear LM7812 does. I've used AL8805's in the past and even LM2596's, so am open to ideas as long as they're not end of life components which will be hard to source later. Just need a schematic and formulas for 24vdc in - 7vdc out. Milestones will be paid: 1. 50% on supply of the circuit details 2. 50% on completion of testing the circuit (will need 3 days to get parts and build it)
