Re: 🎉 Arduino Day Philippines 2026 — Circuitrocks as Keystone Sponsor
Wow! May Arduino Day pala dito sa PH! First-year ECE lang po ako, free pa po ba kapag attending? Kahit observer lang muna 
Tinatanong ko rin sa adviser ko kung pwedeng credit yung attendance for tech immersion requirement. Sana go!
