Ez Battery Rechargeable Joystick/Gamepad for Vorpal Hexapod

cults3d

This is the remix of Vorpal Hexapod gamepad. Unlike others, it's powered by a 3.7V 18650 lithium battery and the board we use has sufficient 5V output pins for each component. With a lithium battery, it provides reliable and strong power to components. Lithium batteries are chargeable, making them more economical and cost-effective in the long run. Battery recharging is easy by simply plugging in a 5V power source into the USB port of the board. Additionally, hexapod movements are controlled by a joystick switch instead of a keypad. The functions of the 4x4 matrix switch remain unchanged. Video Demos https://youtu.be/Nv6KPV5iczc Software Arduino sketches on GitHub - upload test.ino to check wiring correctness of the matrix switch and joystick switch first; open the Serial Monitor to see the button and joystick switch respond; if everything is correct, upload firmware.ino. To successfully upload firmware.ino, the SD reader library SdFat needs to be installed. Electronics To build the gamepad, you'll need the following components: A HuaDuino board - it's an Arduino Nano compatible with enhanced features. It integrates everything on a single PCB, making it easier for people to create bots with it. The embedded battery charging circuit makes battery charging more convenient, and it's inexpensive, so it's our favorite board for projects. This combo kit will make sourcing other components much easier. A joystick switch A 4x4 matrix switch pad - there are two variations; the one we used is shown in the photo, and another is available on Vorpal's webstore, so pick the correct model to print. An HC-05 Bluetooth module (set to master mode, if your robot's HC-05 is in slave mode) A MicroSD Card Reader - this can be optional as it doesn't affect the control of the robot in gaits/dance/fight mode. A buzzer - optional if you don't need a beep sound An 18650 lithium battery, use this battery clip to hold it 8 M2x6 tapping screws 4 M3x14 screws 17 dupoint wires The 4x4 matrix switch, dupoint wires, micro SD card reader, and HC-05 can also be found on Vorpal's webstore. Wiring The connection of components to the board is as follows: Joystick Switch: VRX_PIN -> A0 VRY_PIN -> A1 SW_PIN -> A2 VCC -> 5V GND -> GND 4x4 Matrix Switch - there are two variants: 8/C1 -> D2 7/C2 -> D3 6/C3 -> D4 5/C4 -> D5 4/R1 -> D6 3/R2 -> D7 2/R3 -> D8 1/R4 -> D9 HC-05 Bluetooth UART Module: RX -> A5 TX -> A4 VCC -> 5V GND -> GND Micro SD Card Reader: CS -> D10 MOSI -> D11 MISO -> D12 SCK -> D13 VCC -> 5V GND -> GND Buzzer: Positive polar -> A3 Negative polar -> GND
