microcontroller design

I want to make a PCB (based on arduino NANO) for the management of a nanogrid consisting of a PV Solar and Wind Turbine and two storage batteries it has to contain current/voltage sensors along with ADC that send the data to arduino NANO for handling (decision making and Data storage in...

Hello all, I am currently working on a project where I have to divide a 100 MHz frequency by n. where n could be any integer1,2,3,4,...9. where I want to give these n integer from external keypad or any software control. Is it possible to do it with #microcontroller based system or FPGA...

Hi, I want to add to design LED indication for Rx, Tx over pull up resistors, please refer picture for more detail. I do not know is this good idea or is better to add two dedicated outputs on MCU only for RX, Tx LED management. Please share pros and coins for solution on picture. Thanks.

Hi, An initially charged capacitor in a resonance circuit undergoes periodic voltage reversal (blue line), as shown below: A possible circuit to address this problem uses 2 capacitor banks & switch modules, as shown: C₁ and C₂ represent metallized film capacitor banks of equal capacitance...

Dear all, this hobby project I setup is using an encoder to make the stick to be 90 degress which is at 1500 steps (0 degrees=perfectly horizontal using PID control). My encoder counter code is obtained from video here and I have tested it which works perfectly well. Since this encoder is 1200...

I'm working on a custom microcontroller design based largely off of NXP's K64 FRDM boards as part of a larger project, and recently (despite the date on the schematic) finished what may be considered "version 1." As a brief background, this board will have a sibling layout embedded into a larger...
