Hi im 100% new to Arduino and trying to build my first project that I purchased from someone it’s a game
It’s called plasma ball this is the diagram and I fallow it to the " T " but when im trying to install the code its not working. can anyone please help me with it. what it does when u hold both of the plasma ball together it trigger actuator up when u touch it and when u let it go its go down but the problem when I try to upload the code i`m keep getting error messages can someone please help me with it and see why its not letting me upload the code im using the Arduino UNO r4 wifi thank you : (
This is the code –
**
* Dual Plasma Ball
*
* This sketch is an escape room puzzle in which players must simultaneously place their hands on two plasma balls,
* in order to make a linear actuator rise up. When a plasma ball is touched, the current through it rises, and this
* is detected using an IN219 sensor.
