Hi! I am Divya, a rising sophomore at Saratoga High School.

For my starter project I built a Minty Boost phone charger. Using a schematic I found online, I soldered all the components provided in the kit onto a PCB board. When connected by USB, a phone will be charged.

My main project was a hand-gesture controlled robot. Flex sensors are attached to a glove. When flexed or bent, they send a number through an Xbee, a wireless communication device. A receiving Xbee is on the robot, which will do certain functions based the data received.

My favorite part of Blue Stamp was the guest lectures by real engineers in the industry. I thought it was really cool how every person that came had a completely different story but, were all participating in really cool projects that could potentially impact a lot of lives. During my experience in Blue Stamp, I realized I for sure wanted to go into the tech industry. I am interested in robotics, electrical engineering, and computer science. What I took away from Blue Stamp was my love to fix problems. It is the most exhilarating feeling being stuck on a problem for days or weeks but then finally solving it after hours of research.

Bill of Materials


In my final video, I have my hand-gesture controlled robot. Since the last milestone, I created a circuit for my two servos. The flex sensors output values onto the arduino on my glove. An arduino is a microprocessor or small computer. The values get sent wirelessly to an arduino on the robot through wireless communication devices called XBees. Based on the values being received, the arm and claw open and close. I also tried making a circuit for my two motors however, they didn’t work. I hope to eventually make the motors work.

In my second milestone, I made the robot and the glove. First I had to get my metal base cut. Then I drilled holes into the aluminum for wheels and the claw. To mount the motors I had to use hose clamps. Then I made the glove. I had to learn how to sew. I sewed the flex sensors onto the glove and put electric tape for extra support. I then attached wires to the ends of all the pins on the flex sensors. The wires led to power, ground and analog. I soldered the wires together and plugged them into an Arduino. Then I attached the Arduino onto the glove using velcro.

Divya A – Milestone #1


In my first milestone, I made a light turn wirelessly using xbees. I, first had to configure the xbees which took a while. Then I had make a circuit that turns on a light. I coded  program that when given a certain input it turned the light on and off. I typed a letter into my computer which was sent to the other xbee which was connected to an arduino. The arduino had the code and read the input. The specific input then turned the light on and off.
