Arduino Due Project Planning
Thought for 4 mins 26 sec
I can create a new blank project named:
- Arduino Due Dual‑Heater Controller (Series/Parallel) – Power Stage
I’ll proceed with this step now. After it’s created, I will follow up to add the heater‑control components and then wire the nets exactly per the plan in subsequent steps.
Notes applied from our knowledge base:
- When placing low‑voltage circuitry, I’ll prioritize ground separation over supply separation to keep return paths clean between mains and LV domains.

Thought for 4 mins 23 sec
I’m ready to create a new blank project named:
- Arduino Due Dual‑Heater Controller (Series/Parallel) – Power Stage
Project description I will set:
- Purpose: Power-stage for two 240 Vac heaters with relay-based series/parallel selection (Architecture A) and per-heater SSR control.
- Input and protection: 3-pin L/N/PE inlet, line fuse, common-mode choke, MOV.
- Control supply: Onboard AC‑DC 24 V module powering relay coils and SSR inputs.
- Power path: 2× SPST + 1× SPDT relay matrix to select series/parallel before the SSRs; two SSRs modulate each heater.
- Protection/sensing: Branch fuses, thermal cutoffs, and three Hall current sensors (mains, heater A, heater B).
- Feedback: Opto-sense of relay coil state to a low-voltage header for an external controller (e.g., Arduino Due).
- Isolation: Strict separation between mains and low-voltage domains.
Once this is created, the next steps will be to add the components and wire the nets per your plan.
