If its ok for you? im planning to expand the use of arduino by using some inputs to control the individual actions of the relay. The meter automatically provides an accurate readout of SWR for any power level between 10mW and 1000W. I2C Pins SDA and SCL connected to A4 and A5 of arduino uno board because these two are I2C pins in uno board. » Arduino AirLift Shield ESP32 WiFi co-processor arrives at Adafruit » COULOMB TRANSISTOR — A NEW CONCEPT WHERE METAL NANOPARTICLES ARE USED IN PLACE OF SEMICONDUCTOR ARDUINO RF power & SWR meter. I decided to re-visit a very old project I had from high school and give it a refresh. Analog Devices AD8318 Datasheet and Product Info; Here is a wiring diagram of my RF POWER LEVEL METER. Homebrew SWR and power meter First of all, this SWR meter in this article is not exactly homebrew, as I based the circuit on the schematic in the excellent book Arduino Projects of Amateur Radio. It endeavors to provide the products that you want, offering the best bang for your buck. I'll explain what it does, show its specs and share an Arduino project example that you can take and apply to your own projects. Arduino Pro mini sits in the center doing all the work. Before moving to fix the reception on my Pi, I now first try to maximize the reception on the receiving Arduino. The nRF24L01+(nRF24L01p) is a single chip 2.
