Example: Arduino Pro Mini. First, let’s assume a circuit design that uses something like the Arduino Pro Mini. The maximum current draw of the Arduino is 200mA. It’s unlikely that the Arduino itself ...

With the constant current source and a little bit of ohm's law, we can calculate the resistance value quite easily. In the schematic, you can see a formula that is used to calculate the current limit ...

While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies o… ...

Microcontroller based constant current driver. Based around a LM2596S drop down regulator (because these complete modules are cheaper than buying the components) and an Arduino Pro Mini. The repo ...

It was based on a constant current source that is controlled by a DAC hooked up to the Arduino. By measuring both the resulting voltage and current of the load, the system can dynamically adapt to ...

So if you are in a plan to make your own open source microcontroller platform – Arduino, no doubt, you need an AVR chip with pre-charged bootloader! Advertisement. This part of AVR tutorial will teach ...

This paper presents the design and validation of constant current DC-DC converter modules which provide constant current operation for driving an LED array that is comprised of multiple wavelength ...
