Introduction: Electric Skateboard Remote
Join my journey, hopefully you will learn something.
This will not be a step by step tutorial. It will be more a showcase what I have used, how I did it and I'm sure you can do it to.
I even recommend you NOT doing it exactly like i did it. This design is not flawless i'm sure you can improve a lot of things. See this more like a great resource if your planning on building a remote.
1x OLED SSD1306 Display I2C
Some kind of hardware for detecting throttle. In my case i used a Joystick i had laying around. A better choice is to use a Linear Ratiometric Hall Affect Sensor. If you go with the Hall effect sensor, don't forget to get a magnet.

Lets not forget the brains of the operation
2x Espruino MDBT42Q
We will need a battery; in my case i used the most thicc battery i could find. I have enough battery anxiety from the longboard itself. Would totally work with a smaller battery.
1x 18650 LION Battery
1x LION Charge board
I recommend getting at least one tactile switch and one slide switch. The more switches the more options you have when playing with your firmware.
Tactile Switch >= 1
1x Slide Switch
Step 1: Print the Case / Make the Case / Buy the Case
Paint the enclosure
Step 2: Mount the Display
I used paste that hardens after a few minutes to stick the display.
Step 3: Assemble Battery Module
Step 4: Wire Up the Brain
I don't have a schematic but i'm sure you can figure it out.
If you want to be able to read the voltage from the battery you will need to make a voltage divider circuit to make sure the battery voltage doesn't exceed 3.3v.
Step 5: Uplod the Codez
Step 6: Assemble the Enclosure
I used double sided tape to stick the to pieces together
Step 7: Profit
