In the year 2016, I have written an Instructable on "Arduino Capacity Tester - V1.0" which was a very straightforward and simple device. The earlier version was based on Ohms Law. The battery to be tested is discharged through a fixed resistor, current and time duration is measured by Ardu...
For uploading the program to the Arduino Pro Mini board, we need an USB to serial UART interface which can be connected to the programming header. Before connecting it to the computer USB, first we must turn on main power of the device, because otherwise the power coming from the...
DIY RGB Tube light is a multi functional tube light which can be used in photography, light painting photography, film making, gaming, as a VU meter and more. The tube light can be controlled by Prismatik software or by a push button. These tub lights are made using a Arduino Nano and...
The extension board (panel board) contains 12 LEDs (ws2812), a power button and two light sensors. Because the LEDs do not have a port number, we have to access them via the Arduino pin number. The following code creates an LED object (meRGBLed), and during the setup the pin numbe...
