In ECE 387, Embedded Systems and Design, we needed no make a toy which incorporated two chips. I incorporated a transistor and a Na 556 chip. During the middle of the semester one of my classmates Adnan Obissi and I did a lot of research on the Na556 chip. To incorporate this knowledge I desided to take my love for photography and make a timer for a camera. This timer however is different than a regular timer, because I used a photo sensor to detect motion. Based on this motion the timer would start, and then once the timer set of the transistor the camera would start taking pictures.
