1000 steps Servo motor
https://www.electronics-lab.com/1000-steps-servo-motor/
TheSuperSewcio @ instructables.com shows us how to control a servo motor in high precision using Arduino: In many project like CNC machines people use stepper motors. They are probably always more expensive than servos. They can rotate 360°, 1 step = 1,8° (mostly). Servos can rotate only from 0° to 180°, 1 step = 1°. But […]

In this project, you’re going to build a web server with an ESP8266 to remotely control an RGB LED. This project is called ESP8266 RGB Color Picker. ESP8266 RGB Color Picker – [Link]
Running NodeMCU on a battery
https://www.electronics-lab.com/running-nodemcu-battery/
ESP8266 low power consumption revisited: Using Wi-Fi is a convenient way to link your newly created IoT device into your existing IT infrastructure – including cloud services – but it also has a drawback. Wi-Fi’s demand for power usually makes battery operation impractical for any real deployment. I have been able to get around this issue for most of my […]
384:LED – Mini RGB LED array
https://www.electronics-lab.com/384led-mini-rgb-led-array/
Mini (1.44” x 0.94” or 24mm x 37mm) 8X16 RGB LED Array. 128 RGB LEDs with three LED chip each gives 384. For this project I designed two PCBs. A control PCB and a LED PCB. My goal was to fit them both in a small panel inside a 5×5 cm square to use cheap […]
Oscilloscope Vertical Position and Offset explained
https://www.electronics-lab.com/oscilloscope-vertical-position-offset-explained/
This video describes the function of the vertical position and vertical offset controls of a modern digital oscilloscope. It shows how using the offset control can provide valuable visibility of the DC bias and small signal waveform simultaneously, which can be very valuable in many applications.

Piggybacking OLED display on WeMos D1 Mini
https://www.electronics-lab.com/piggybacking-oled-display-wemos-d1-mini/
Daniel Eichhorn build a mini OLED display weather widget using WeMos D1 Mini board. Inspired by Mike Rankin’s (@mikerankin) beautiful crossovers between an ESP8266 ESP-01 and an 0.96 Inch OLED I2C display I decided to try if there wasn’t an easy hack to marry the two components with as little soldering as possible. After turning, […]
WiFi Weather display using a Wemos D1 board and operweathermap.org website
https://www.electronics-lab.com/wifi-weather-display-using-wemos-d1-board-operweathermap-org-website/
educ8s.tv published a new project, a ESP8266 Wifi weather display. In this video we are going to build a WiFi Weather display with the impressive Wemos D1 board. The board uses the ESP8266 chip in order to connect to the internet and we are going to program it using the Arduino IDE. The project gets […]
Dual axis solar tracker with online energy monitor
https://www.electronics-lab.com/dual-axis-solar-tracker-online-energy-monitor/
by geo bruce @ instructables.com: The features of this solar tracker are: Solar tracking: making sure the solar panels are aligned to the sun as long as possible. Energy monitor: This measures the voltage and the current generated by the panels and calculates the generated Power and Energy. Data logging: this sends the data from […]
