This drawing will display RF power and SWR readings from any SWR bridge, such as the ‘monimatch’ type. Since this type of bridge, called ‘monimatch,’ varies with frequency, the meter needs to be adjusted for each bandwidth. My main focus was on VHF/UHF/SHF, so I had planned for 6m, 4m, 2m, 70 cm, 23cm, and […]
Arduino text‘in. Key Features: 24 relays controlled by 4 I/O lines! Cell phone text using your Arduino. This project hacks a cell phone to text using normally open relays. After investigating cellular modules on the internet I decided it looks not only rather pricy, but also like a possibility that even after I had it […]
I’ve just completed my second Arduino project, a sound level detector which sets off an “alarm” when there’s the sound level is to high for too long. I built it for use in a school that wants to provide visual feedback to students when they are being too loud. The “alarm” is a string of […]
My Lumix GH2 Micro Four Thirds camera not only shoots fantastic high definition videos, but with inexpensive adapters I can use it with older manual lenses that are cheap and often very high quality. I shoot a lot of performance videos for my daughter’s dance studio, and I use an f3.5 Nikon 28-85mm zoom lens because it provides a […]

This project slightly modifies the Google Android sample app called “Bluetooth Chat” so you can type a message in the Android app and that same message will appear on an LCD attached to an Arduino Uno. Functionality: Android talks to Arduino 1. Run the Android “Bluetooth Chat” sample app (after we modify the app in […]

Narrative Arduino is truly remarkable; I have a deep fondness for it. It can be likened to the “Lego” of the electronics and automation world. Presently, I’m engrossed in a project where numerous MCU boards are orchestrated to form an interconnected network of processors, aptly named NetP. These boards establish communication via the i2c bus. […]
Salutations and thank you for visiting The IoT Projects. This guide is intended to show the ways of building the Dual Axis Solar Tracker Arduino Project using LDRs and Servo Motors. The publication can be divided into seven parts, which can determine an extensive guide on how to build the project. Thus using light sensing […]
