Light Up Your Robot Card
I recently won an Instructables contest. They sent me an Instructables' robot t-shirt, book, stickers and a picture of the Instructables robot. On the other hand, when I was thinking about simple paper circuit ideas and I wanted to build a circuit on the picture of robot and make their eyes using leds. A very different and fun robot appeared. Let's get started!
Step 1: Required Materials
- Red 5mm LED (2)
- Copper Tape
- 3V CR2032 Coin Cell Battery
- The picture of Instructables robot. ( I wanted to make this project with the picture of Instructables robot. You can draw your own robot if you want.)
- Adhesive tape
Step 2: Drawing Circuit Diagram - 1
Put the leds on the robot’s eyes as shown in the picture.
Step 3: Drawing Circuit Diagram - 2
Let's draw the circuit as shown in the picture. Bring the minus legs of the leds together and do the same for other legs (+) as shown in the picture.
Step 4: Drawing Circuit Diagram - 3
Stick the copper tape by following the way of the circuit. Stick adhesive tape on the legs of the leds.
Step 5: Drawing Circuit Diagram - 4
Glue half of the 3V battery with adhesive tape as shown in the picture.
Step 6: Drawing Circuit Diagram - 5
The robot's eyes will light up when you press the copper tape onto the battery. If it doesn't, check the circuit.)
