RAMPS 1.4 3D Printer: Bluetooth Setup 1, Voltage Divider and Wiring

- čas přidán 7. 09. 2024
- The RAMPS 1.4 3D printer controller is capable of using a Bluetooth module to connect to the host. However, the most common Bluetooth adapters use 3.3v logic. Since the RAMPS uses 5v logic, a voltage divider is required to protect the Bluetooth adapter from damage. Luckily this only costs around $1 and takes a few minutes to make.
This short video shows construction and wiring of the voltage divider used to safely connect the RAMPS 1.4 3D printer module to an HC-05/HC-06 bluetooth module in order to enable wireless connectivity. The voltage divider goes between the TX of the RAMPS board and the RX of the HC-05 bluetooth module. Schematics and details of this set-up can be found in the Bluetooth section of the Reprap wiki here- reprap.org/wiki...
Parts Needed-
1- HC-05 (or HC-06) bluetooth module
4- 10" female-female breadboard jumper wires (AKA DuPont cables)
2- 1" pieces of 1/8" heat shrink.
1- 1" piece of 1/4" heat shrink
1- 1k Ohm 1/8 watt resistor
1- 680 Ohm 1/8 watt resistor
solder and soldering iron
Note - This video covers the physical wiring & connection only. In the next video (here - • RAMPS 1.4 3D Printer: ... ) I go through how to configure the Bluetooth controller and the RAMPS so that the baud match and test connectivity from the host PC.
Can't wait for the next video , thanks for doing this
Thanks for watching! I'm in the process of building a Kossel Mini and am planning to put the whole build up...
Charles Werbick i was impressed , just order a NEW FT232 adapter as i thought i had two but can't find them Already have the jy-mcu
***** Yeah I use them to enable telemetry via Bluetooth on my RC multi-copters. Total serendipity that they work on the Reprap too!
same here lol how funny i use them to program my GPS module and telemetry on my quads
Thankyou very much Charles so very helpful but could you please tell me what sketch is that ,that you use in part 2.
Thank you Alan.
I wanted to do this coordination with the frequency Converter OMRON did not work
Euhm, arduino does provide the 3,3 volt?...
But not on the logic ports
Hey Charles!
Really informative video mate i am having trouble with following error:
#error "BLUETOOTH is only supported with AT90USB."
Using Ramps 1.4 with Arduino Mega 2560 when compiling after un commenting this line:
// Enable the Bluetooth serial interface on AT90USB devices
#define BLUETOOTH
it gives above error please help!
You have to programme the bluetooth first
