Discover the new world of electronics with TechTOnions. We provide projects on Arduino, ESP32, and STM32 to help makers, engineers, and hobbyists explore and innovate. Join the electronics revolution today!
If you never used an oscilloscope before then, this project is for you. Thanks to the project scoopy, now we can use our Pi-Pico board to build our oscilloscope.
This oscilloscope is a great start towards exploring your electronics project insides. This project can be the cheapest way to own a digital oscilloscope. Let’s explore what can be done with this.
Recently Raspberry pi foundation has launched the Pi Pico microcontroller board. This board had quickly gained the attention of the community due to its low cost and high performance.
In this tutorial, we will explore the Pi Pico board and, we will learn to program it using Arduino IDE.
WhatsApp is now an essential part of our day-to-day life. Receiving any alert messages from ESP32 directly to WhatsApp would be great.
Therefore in this tutorial, we will show you how to send any messages directly to your WhatsApp.
We will be using Arduino IDE for programming ESP32.
In this learning guide, you will learn about Operational Amplifiers (OP-AMP). Operational amplifiers are a fundamental part of analog electronics.
Learning characteristics and knowing different usage of operational amplifiers can help you get started with opamp-based projects.
Stick around with us in this analog journey of an OP-AMP.
ESP32-CAM has everything to build your camera-based IoT projects. But the major disadvantage of the ESP32-CAM board is that it does not have a USB programming connector or any power connector.
For programming an ESP32-CAM board, we have to connect with FTDI converters, and it also doesn’t have an onboard auto-reset circuit.
