I'm working on a school project right now, and I need to convert DC from the arduino to AC because the SSR we ordered says in the product description that it uses DC, but in the wiring diagram it says AC and it wasn't working with DC. Alternating high and low voltage with a low delay on the digital pins won't work because low isn't actually 0 and we need true zero to close the bridge.

This is the link to the SSR we ordered, if it helps: https://www.amazon.com/HiLetgo-SSR-60DA-Single-Semi-Conductor-24-380V/dp/B01MSTFKIP/ref=sr\_1\_2\_sspa?crid=167Y1HFWJE9W&dib=eyJ2IjoiMSJ9.Djvp1FJ9NzmFS0iDVnrgI6N8aFTj-InspTt\_vtwFNy2ErhiSRYlUnRFqS7OpUzuRYqj6hVVUEt8omqDVhZ1HPnk6ToiuqZ5to11uRWGZ3QwI1Z5FfFAXWAnkcC3pKgMIhBb6M7XJCZr\_Cr7cywXKBujgGrfwaTGBXUhq9vqUaFcSA4vvSRM7KgusYYTe8H7ldLcBt9mqNyBHmJ\_2AUmF3ylTuitFzzC\_MsNZKvic2qQ.ePfAzwPy8jMRM\_GRgSRgZ\_uhVMPCSey8BMu1TBynjJ8&dib\_tag=se&keywords=solid%2Bstate%2Brelay&qid=1774872290&sprefix=solid%2Bstate%2Brelay%2Caps%2C164&sr=8-2-spons&sp\_csd=d2lkZ2V0TmFtZT1zcF9hdGY&th=1
