Bargraph Voltmeter 0-5V DC range – PIC16F686
Tiny Bar-Graph displays provide a Red color bright, easy to read display of Voltage range of 0 to 5V. This Bar-Graph has 20 segments in single color and display 0 to 5V DC. The Barograph Voltage monitor is based on PIC microcontroller with 10 Bit resolution ADC. This high performance...

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...

Running NodeMCU on a 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...

384:LED – 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 5x5 cm square to use cheap Chinese Manufacturing...

Oscilloscope Vertical Position and 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...

Piggybacking OLED display on 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...
