**Assalamualaikum Everyone.** I am [@imranhassan](https://steemit.com/@imranhassan) From [#Bangladesh](https://steemit.com/trending/bangladesh)

Steemit Family, I am @imranhassan, from Bangladesh. I have been working on various technology and circuit projects on Steemit for several years. In Steemit Learning Challenge Season 23, I worked as a mentor for the Home Repair Club, where I helped many people by teaching them how to repair LED lights, fans, chargers, and other electronic devices. ![🎯 Steemit Challenge Season 25 - Contest Pitch Electronics Project Challenge.png](https://cdn.steemitimages.com/DQmdYeBMQdbtouWMfkh29yMHjSWjyC8CgYykF7JxuTTc9eS/%F0%9F%8E%AF%20Steemit%20Challenge%20Season%2025%20-%20Contest%20Pitch%20Electronics%20Project%20Challenge.png) Edited with Canva. Now, I have come up with a new contest idea for Steemit Challenge Season 25, which will feature advanced circuit parts and hands-on projects. This challenge will be an opportunity for participants to learn the effective use of electronic circuit parts and create creative projects. Main Objective of the Contest:| |-| - To create projects using electronic circuit parts - To create creative and educational projects - To learn and teach — not only to learn by yourself, but also to teach others - To design circuits and create real-life projects 6-week contest plan (1 post per week + 1 announcement post) Each week I will post 2:| |-| - Contest announcement – details of that week’s work - Winner announcement – results and work of the best participants ## Week-wise contest plan: Week 1: PIR Motion Sensor | |-| **Circuit parts** ![image.png](https://cdn.steemitimages.com/DQmbYxWpFF59uYqjkyvY7rzkWtF5We1iY46e8E62Thrdkww/image.png) - PIR sensor module - Arduino or ESP32 microcontroller - Relay module (if external devices need to be controlled) Challenge: To create a manual or auto-triggering system from a PIR sensor, which detects moving objects and generates an output. Example: To operate lights or create a security system through a PIR sensor.
