Theory Channel capacity Shannon-Hartley law: where C is channel capacity [bps], B is bandwidth [Hz] and S/N is signal/noise ratio. Example: dPMR (C = 4800bps, B=6250Hz). So S/N must be at least 0.70. Number of bits/symbol needed Nyquist's Theorem...
This project is sponsored and supported by JLCPCB - Manufacturer of Printed Circuit Board and offers 5 free PCBs of Arduino Compatible Board. For this project, we'll use the JLCPCB Arduino Compatible printed circuit board presented below. You...
Step 1 This CNC is based on GRBL0.9 Firmware and CNC V3 shield GRBL is Hacked for Z-axis Servo. CNC Shield & GRBL combinly works very preciselyIt is loaded with very useful functions like Hard limit, Soft limit, Homing, etc This is about how to...
This project is a notes-to-selves (myself and others) about the various aspects of controlling lots of LED lights using network protocols such as DMX, Art-Net, sACN/E1.33, king-net etc. Generally this would be considered Lighting/Effects Show Control,...
Arm is RISC based architecture which can be seen a lot in embedded domain. There are billions of arm devices currently active. It ranges from automotive to smartphone processor and now in your laptop thanks to Apple. That being said let us dive right...
In this IoT project, I have shown how to make ESP RainMaker IoT Project using ESP32 to control relays with Google Assistant, Alexa, Bluetooth, IR remote, and manual switches. real-time feedback. So, you can easily make this home automation project at...
In this tutorial, we are interfacing the fingerprint sensor with Arduino. Let’s explore the working of R307 fingerprint sensor. Here I will show you how to enroll the fingerprint inside the Flash of sensor and finally we will match the fingerprints using...
Whenever we have to use video output in any IoT or robotics project then Esp32-Cam module comes into mind. It is the one which can fulfil all the needs and has comparatively low price than other modules available. The good this is we can use SD card...
Just read a passage about Nextion HMI Display, thought it kind of interesting to share with you guys. The following is the one I just mentioned: enjoy!With the complexity and sophistication of embedded systems today, a necessary component is a user interface...
There are many monochrome OLED display modules available for really reasonable prices out there. They can be really useful for a small and simple display in a project. However, many libraries available for driving them are rather big and slow. In this...

After we built Poorna, our base model, we had a bit of a problem. We had engineered a lot of flexibility into our design. Folks asked us, “what can you do with this?”. My typical response, invariably, would be “a lot – anything,...
From the Latin, "Docta Vox" meaning "learned voice" or something like that according to Google Translate. It sounded cool and I'm bad at naming things anyway. So there you have it. This project uses Processing with STT (speech to text) and TTS (text...
This project demonstrates a basic web application example with the CC3200 development board, AK9753, and TMP006 sensors (web-application link.)I have developed a simple web application for the CC3200 development board, an AK9753 Human Presence...
This project was developed in partnership with Robô Lúdico Schooland JLCPCB Factory that offers 5 free PCBs of Arduino Compatible Board. In commercial establishments, it is very common to use panels with LED arrays to display some...
