RC tank on Arduino © GPL3+
DESCRIPTION

The tank gun shoots with plastic balls. Laser sight. Headlights. Assembled based on the Arduino Nano platform. The chassis is made on the L298N driver. As a rotary tower, a rotary bracket on two servos is used. 4 18650 batteries provide long battery life. Radio module APC220 or NS-12. Powerful loads are controlled using the Darlington ULN2803 assembly.

The chassis and lid of the tank were purchased at the Sinonig store.

See chassis overview in this video:

The tank gun was also purchased at the Sinoning Store.

As a tower, a swivel bracket and two servos were used:

A powerful home-made power bank was used for power.

Two UART APC220 modules are used for communication

To control the motors used driver L298N.

Servos are powered by the L7805CV driver

Tank gun and headlights powered by Darlington assembly

INA219 module is used for battery monitoring:

For radio control uses a universal remote control based on arduino mega:
