atmega328p

Hi all, I have basic knowledge in electronic engineering but feel a bit rusty since I haven't been doing this for a couple of years. The project: I've created a PCB to program empty Atmega328P chipset, when connected to Arduino (I'm using ELEGOO UNO R3) It houses a TQFP32 to DIP32 IC test...

I have a device that works on **3V battery** (2 D size cells) now I want to debug it so that all the devices work correctly. My device consist of **atmega 328p**, running on 08 MHz Crystal which gets readings from ADXL345 for 2 seconds and then store it in 25Q64FVSIG flash memory and then RFM96...

Hello everyone, I am working on a small project using ATMEGA328 (AM for short).. I use a voltage regulator to power the AM and then one of the output pins of the AM is connected to an LED+ resistor and Ground. I power my AM using an L7805 voltage regulator and I noticed that when the ground in...

Hi All, I am designing a ATmega328P based PCB control board that has a function of sending and receiving discrete digital signals to and from a PLC. The PLC has sinking outputs. The PLC can accept sinking or sourcing inputs. I want the PCB to output Sourcing (PNP) signals to the PLC. (mostly...

I would like to make my own PCB for a diy drone project. I've already made a schematic, but this is my first experience with designing PCB and I'm not sure if everything is wired correctly. I also plan to add a voltage divider, to measure battery voltage.

While measuring a mains capacitor in haste, I forgot to discharge it first and ended up damaging my component tester! Before anyone says it, yes I know I should have discharged the capacitor first! Anyway, I have replaced the ATMega328P microcontroller but I can't seem to find a firmware...

Hello partners I am an engineering student and I am doing my graduation project. I try to send information from the Photovoltaic Panel to the computer. In order to do this, I made a design of a circuit that can measure the voltage of a panel that is generating between 25 and 44 volts. This...

I'm having a hard time including interrupts into my cases for a traffic light code. The interrupts are supposed to start a sequence of events but my brain is just fried on how to go about it.

Hi all, I've been having a very big problem since 2 days. I got a brand new Atmega328P U-TH IC and made a custom board around it. Due to covid lockdown I am not able to purchase any programmers like USBasp, so I decided to use my Arduino UNO as ISP programmer. However, When I tried to burn the...
