Servomotor is one of the most common electronic components, and you can control the servomotor position by only using the value returned from analog sensor. Servos also the easiest way to get you started with a microcontroller related with motion.

Those components you needed are:

• Breadboard
• 22-AWG hookup wire
• Arduino microcontroller board
• 10K ohm resistors
• Flex sensors, and of course
• RC Servomotor

Ok, let’s start the project. Firstly, you need to connect power and ground on the breadboard to power and ground from the microcontroller. Use the 5V and any of the ground connections on the Arduino module (Please refer the above figure). Read more »
