Then VIN must be larger than 6.5 volts? Not certain but I think so.It is an Arduino board. Vin is voltage in
No. I am coIf this is arduino like, with an on board regulator, then as said above Vin needs 7V+ and your 7805 output should be connected to +5V pin, not Vin.
maybe this will help clear up what I am attemptingIf this is arduino like, with an on board regulator, then as said above Vin needs 7V+ and your 7805 output should be connected to +5V pin, not Vin.
It is a simulation. Nothing has been assembled yetWhat does "Convergence failed" refer to is this a simulation or a real-world circuit assembly?
But your simulation has a box with 3V3, 5V, and Vin pins. The bare chip has only the 5V pin. What exactly does your simulator think it is simulating?maybe this will help clear up what I am attempting

All i was trying to do wasadd the voltage regulator per the building your own Arduino. I am thinking the simulator is treating the Arduino as an assembler board. Was just using the Arduino to utilize the 4017But your simulation has a box with 3V3, 5V, and Vin pins. The bare chip has only the 5V pin. What exactly does your simulator think it is simulating?
Correct. I guess that is what I was trying to say. The simulator only had the single ArduinoIt looks to me that you’re trying to simulate a DIY Arduino board with an “Arduino board”. What you want to use is an AtMega338P in your simulation circuit.
But what I said was that you don’t want an Arduino. You want an ATMega328. The two aren’t the same. One is a microcontroller board or system. The other is a chip, which the board is built withCorrect. I guess that is what I was trying to say. The simulator only had the single Arduino
What I am attempting to do is have the atmega328 chip a 328p in this case on a board. Use my Arduino uno to upload a sketch onto the 328p chip. Then the chip will run the sketch as designedBut what I said was that you don’t want an Arduino. You want an ATMega328. The two aren’t the same. One is a microcontroller board or system.

Yes. A diy Arduino assembly if you will using the atmega328 chip. In a nutshell I have some atmega328 chips a bunch of capacitors and other parts I am finding a use for.So I hear that you want an Arduino board powered by an external 7805 (and not use the internal voltage regulators).
The 5V output of the external regulator should go to the 5V pin of the Arduino. As others have commented, connecting the output to the Vin pin won’t work. The Arduino board won’t be powered.
