In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...

An optocoupler tester is a small device that helps verify whether an optocoupler is functioning properly or has failed. In labs and repair work, optocouplers often fail without clear signs. They may ...

Pinpointing the minimum and maximum transient noise bandwidth for a transient noise simulation is a non-trivial task. But these algorithms can help ease the challenge and ...

Inspired by South African and Australian builders pushing record-braking speeds with their larger drones, this little one packs an ESP32 at its core inside an aerodynamic bullet frame, driven by four ...

Decade resistor for strain reliever. Genius delivery person! Generosity on the woman? They accidentally dug a snow crystal? Whipstitch top to stop trying save them? Stiff neck virus? Expedite up close ...

Trogon and toucan. Teens drink and revel in bad form. Enhanced campaign list. Salespeople create value added reseller? Transformative use of lambda sequence? Spotted an incorrect order? Possibly ...

A compensated Pt100 RTD circuit has 1 mV/°C DMM output, with linearization via positive feedback, pending Part 2 ...

Abstract: This work proposes a novel resistor-floating-resistor-string digital-to-analog converter (RFR-DAC) architecture with a 10-bit resolution for liquid crystal display (LCD) driver applications.

A maker shared an electronics project on Digikey that explains an automatic system for recognizing and organizing resistors using an Arduino Uno Q. Zach Hipps did the work and looked for methods to ...

This is the primary documentation for the MoveIt project. We strongly encourage you to help improve MoveIt's documentation. Please consider helping improve the tutorials, port old ones from ROS 1, and ...

Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost ...
