Hi, i want to build a rf remote control for my backyard water pump.
I want the remote to be as easy as it can so my parents will understand it quickly.
As input i want to use either 1 single switch either 2 push buttons, no switch for the power, because everyone will forget to close it and the battery will run out quickly even if the arduino will sleep.
Also... I want to somehow boost the voltage for the rf emitter module so it will be powerful, i thought about using one of the pins for the switch of the boost converter in combination with a inductor and a cap.. Only to power the rf module for one message, on or off
And remember i'm using attiny board which will drain more current the nano in sleep even if i remove the regulator and the led.
It will be nice if there is a solution which the arduino qon't be connected to power all the time
Like the ATMega328p described in Nick Gammon's excellent article, the ATtiny85 will run for years on a coin cell, using almost all of the same approaches. See the ATtiny85 data sheet.

let's imagine that i can make digispark attiny to consume as less as the 328p, now i can use buttons to send a On signal and an OFF signal, but how i can boost the voltage for the transmitter (12V max, 40mA, <10ms signal send time) ? and then, can i use my 3.6-4.1V arduino to with it ? (XY-FST - name of the transmitter)
jremington:
3V on the DATA input will activate those TX modules, regardless of the TX power supply voltage.
Then, this is great!, i was thinking that it's working like a mosfet were the voltage need to be equal
Anyways, it is possible to boost the voltage to 12V and store it into a small cap for the rf module to consume ?
