Introduction

HU-046 is an HC-SR04 Ultrasonic Automatic Obstacle Avoidance Intelligent Car DIY Kit. The car automatically advances, and when the sensor senses an obstacle in front, it automatically turns left or right, or even directly reverses to avoid the obstacle and continue moving forward. The sensing distance of ultrasound can be reset by pressing the button.
It’s a DIY kit that comes with various components. User need to install each component by hand. It not only can exercise and improve soldering skills, but also increase the interest in electronic technology. Great for electronics hobbyists, beginners, school and home education.It is a very interesting DIY electronic product that enables users to understand the circuit more clearly and learn soldering skills.

Feature

1. Ultrasonic automatic sensing distance
2. Programmable induction detection distance
3. Multiple exercise modes: Forward, backward, left turn, right turn, rotate in place
4. High simulation obstacle avoidance robot operation
5. DIY Hand Soldering

6. Philips screwdriver
7. Please be patient until the installation is complete.
8. The package is a DIY kit. It needs finish installed by the user.
9. The soldering iron can’t touch the components for a long time(3s), otherwise damaging components.
10. Pay attention to the positive and negative of the components.
11. Strictly prohibit short circuits.
12. Install complex components preferentially.
13. Make sure all components are in the right direction and right place.
14. It is strongly recommended to read the installation manual before starting installation!!!
15. Please wear anti-static gloves or anti-static wristbands when installing electronic components.

Installation Steps(Please be patient and install!!!)

1. Step 1: Install 11pcs 1Kohm Metal Film Resistor at R3,R6-R15.
2. Step 2: Install 1pcs DIP-28 IC Socket at U1.There is a gap mark on one end of the IC Socket and there is a gap mark on the PCB silkscreen where the IC Socket can be placed on. These two marks correspond to each other and are used to specify the installation direction of the IC Socket.
3. Step 3: Install 1pcs DIP-28 IC Socket at U2 in the same methods.
4. Step 4: Install 3pcs 5mm Red LED at LED1-LED3. Note: The longer pin is a positive pole and connects to ‘ + ’ pads.
5. Step 5: Install 3pcs 6610mm Black Button at SW1-SW3.
6. Step 6: Install 1pcs 4Bit Red Digital Tube at LED4. Pay attention to the installation direction of the decimal point.
7. Step 7: Install 1pcs 8*8mm Self-locking Switch at SW4. It is the power switch.
8. Step 8: Install 1pcs 470uF Electrolytic Capacitor at C1.Note: The longer pin is a positive pole and connects to ‘ + ’ pads.
9. Step 9: Install 1pcs DIP-28 IC STC15W408AS Controller. There is a gap mark on one end of the IC and there is a gap mark on the DIP-28 IC Socket where the IC can be placed. These two marks correspond to each other and are used to specify the installation direction of the IC.
