Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk.

The Arduino-driven turret uses two micro servos controlled with pots to move by degrees in X/Y space. Interestingly, [Afroman] doesn’t program the board in the Arduino IDE using wiring.

Behind the pegboard, a single, hardworking Arduino Uno controls three 16-channel PWM controllers that sweep the servos.

An Arduino Nano or a Micro might be the best options If a small board sounds like the most appropriate choice.

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...
