Aruino radio receiver with a standard hand module and teach mode
Budget: €250 – €750 EUR
We need to open a lock with a standard radio hand transmitter from Amazon. I guess 433 MHZ. The reveiver should have a "teach mode" button.
After pressing the button, arduino is in the teach mode for 10 seconds and the user presses a button on the transmittor. After the 10 seconds, the arduiono stops the teach mode.
During the teach mode, I want to flash a LED.
In case of no power, the arduino should still know the signal from the transmitter. Maybe with a memory?
Later on, if I press the teached button on the transmitter, the arduino needs to swich on a relay for 3 seconds but that's not a big thing :-)
Radio distance: 10m
One transmitter should open several linked arduinos at the same time.
Task:
- Find a transmitter on Amazon with 4 chanels
- Tell me requested board, and reveiver module (original arduino)
- Show me the wiring width the "teach button"
- Arduino Code
