Hello everyone, I've got my Arduino Due connected to two load cells, one inductive sensor and some solid state relays to control a machine. The thing is, sometimes when the machine is operating, my laptop returns me "device not found on COM6" so it wont upload the sketch. This stops when i turn off the machine motor.
The arduino is power supplied by a switching power supply and protected with a grounded metal sheet box. All io voltages and currents are within spec.
Do you have any advice for protecting it more?
