I have assembled an Arduino 5V Pro Micro https://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/ProMicro16MHzv1.pdf connected to a 433 MHz RF Transmitter connected to a moisture circuit (see picture). I am trying to send an RF transmission once the moisture circuit senses moisture. The indicator LED on the Aduino and the LED on the moisture circuit both light when moisture is sensed; however, the light fades in and out. I am sure I need steady power to the Aduino for it to function properly. How should the circuit be altered to supply a steady flow of current to the Aduino when moisture is sensed?
