This project demonstrates how to use an ESP32 microcontroller to measure the distance to an object using an ultrasonic sensor and display the measured distance on a 16x2 LCD. The project is designed ...

YouTuber CNLohr has transformed a low-cost 7-segment LCD into a touch sensor, USB interface, and display driver using the $0.10 CH32V003 RISC-V microcontroller. With clever bit-banging techniques and ...

ESP32 boards may be complex for beginners but offer a wide range of features for DIY projects. Projects like a Wi-Fi scanner, web server, weather station, and smart soil monitor are great for ...

Testing was another crucial part of the project. To ensure accuracy, I had to run controlled tests with known air quality levels to calibrate the sensor. I compared the readings from my sensor with ...

This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact ...

It's safe to say that BITalino isn't your average DIY electronics board. For starters, the sensors that spring from the main unit (which comprises the microcontroller, Bluetooth module and power ...

1. This circuit, based on a PIC microcontroller with a few added components, converts a sensor-based voltage into a 4- to 20-mA current loop. Shown is the circuit as originally drawn on a whiteboard.
