EN - This is a digital servo tester using a simple Attiny44 chip.
Code can be downloaded from http://bit.ly/2wBhLwt
(Also need software servo library found here https://playground.arduino.cc/ComponentLib/Servo/ and to program from Arduino need these boards https://github.com/SpenceKonde/ATTinyCore/blob/master/Installation.md)

This PCB is a simple Arduino Nano based Laser Cannon! We here at ACBR ship our Robotic Laser Cannon Kits with an RF Nano (Arduino Nano with built-in NRF24L01), so the laser cannon can be controlled using the onboard joystick, or through the integrated radio chip. Either way, it's a ton of fun. We have these available as full kits with everything you need in our shop online, but we wanted to post...
This board utilize an ATTINY85 chip to control a servo motor using Serial Command, featuring a MOSFET for switching on/off the servo motor, an AMS1117 3.3 regulator to provide power for the ATTINY85chip and a status LED. Program not included. You have to use Software Serial on Port 3 and 4.
Recommend Serial Command: M-Command
This schematic uses two LDRs (Light dependent resistor) to sense the light and a servo motor to automatically rotate the solar panel in the direction of the sun light. The Arduino code is available on [Arduino Solar Tracker using LDR and Servo Motor]
