Ever wondered if a small, low-cost board like the ESP32-CAM can actually recognise objects or even identify Indian currency notes? In this project, the answer is a clear yes. We combine the ESP32-CAM ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Abstract: This study experimentally examined the energy usage of the ESP32 and Arduino Nano microcontroller boards in active and deep sleep (power-down) modes. Both boards were powered by a continuous ...

Abstract: The accelerated development of the Internet of Things (IoT) in Fifth-Generation (5G) networks has highlighted the importance of exploring energy efficiency during run-time. It is imperative ...

The Waveshare ESP32-P4-Nano is a tiny, inexpensive, low-power development board powered by a dual-core RISC-V processor. Available now from Waveshare or AliExpress for around $19 and up, the little ...

I'm using an Arduino Nano ESP32, containing an ESP32-S3 together with an AZ-Delivery SH1106 I2C Display (128x64px). I'm trying to execute an Interrupt every 30sec. However, upon entering the Interrupt ...

Nobody doubts the utility of the Arduino Nano and its many clones, and chances are good you’ve got at least one or two of the tiny dev boards within arm’s reach right now. But as small as it is, the ...
