Now, grab your Arduino Nano, plug in the USB cable, and upload the code that will make your DIY radar system actually work. The code is fairly long and we have included it at the end of this tutorial.

Assemble the circuit according to the diagram on a breadboard or zero PCB. Verify all connections. If programming through Arduino Uno, the USB-to-TTL serial converter is unnecessary. After programming ...

Above you can see the circuit diagram for connections between ESP32 CAM and USB to the Serial Converter FTDI module. Suppose the SerialConveroter you use has options to switch between 3.3v and 5v. I ...

As the GPS module works on the serial peripherals, it can be attached to any software or hardware pin on Arduino. Here, in this design, the software serial pin is used. The GPS module is powered with ...

I tested the usb to serial connected to PA1-PA2 and PA2-PA3 for serial port ,but I am unable to program the chip from arduino 2.0 with this core. ... To be able to select a STlink programmer in the ...

Some Arduino boards, like the DUE which use a Cortex M3 with an integrated USB port, skip the “convert to serial” step. On these boards it is pure USB to USB link from your computer to the ...

Though [David] could have easily used USB OTG for this project, many microcontrollers don’t have the USB-to-TTL capabilities of his Arduino – so this wasn’t entirely in vain.

As seen in the above schematic, a 5-V DC supply from the USB connector (USB) is routed to two 10-Ω/5-W power resistors (R1 and R2) through an SPST switch (S1) followed by an SPDT switch (S2). Here, S1 ...
