Fix bricked (I think) Uno R3

gsd13 — Fri, 22 Jan 2021 17:49:45 GMT

Is there any way possible to fix a bricked Uno R3? At least I believe its bricked. Have removed driver from original com port and reinstalled. No avail. Have tried updating boards in IDE. No avail. It has worked before as I used it as an ISP to flash my 3d printer MB. Could this have caused a problem with the bootloader?

Thanks for any assistance in advance.

Wemos D1/R1/ESP8266 UART communication

embeddedguy — Tue, 12 Jan 2021 09:26:45 GMT

Hi,

I have a specific question about using UART communication with Wemos D1 R1.

I have an Ultrasonic distance sensor which works well with Arduino Mega/ UNO etc. It is based on serial receive.

The problem is I never had success using such boards with ESP based boards like WemosD1R1, ESP8266 generic, etc.

Do you know any useful tips/libraries/tools to make it work?

Hey, everyone! I really need help. We just implemented a circuit that can count and subtract a number using LDR, 74ls192, 74ls47 and 7 segment but after implementing it doesn't work properly while in the simulation by using Proteus the circuit works well. So, we decided to use an Arduino. But I'm having trouble on how to program an Arduino! I'm new to it! The problem is how can I program a system that upon entering a miniature parking lot that has only 20 slots in the area and that can count 1-20 and upon leaving the area it should minus.

Sorry for the disturbance.
