Introduction: Easter Rabbit Radar
A lovely Easter toy and decoration.
With Arduino and distance sensor which controls two organs and LEDs.
Supplies
Arduino nano esp io shield (I used these) but, mast can also be used.
HC-SR04 ultrasonic sensor.
2 SG90 micro servos
2 colored LEDs (WS2812)
wires
Step 1: Relationship Plan
HC-SR04 ultrasonic sensor becotes.
vcc - vcc
trig - 3 pin
echo - 2 pin
gnd - gnd
Motor and LED connection (nano IO shield)
1) 10 pins
2) 9 pin
led) 12 pin
Step 2: Construction
Fotmara cut cardboard sheet that can be colored later.
I used a pre-designed template that I cut on wood. PDF, AI, DXF. file
It can be painted before mounting.
This solution can be used in several versions and for example: Christmas, helloween ......
Step 3: Code
What I used to code was kneaded from two programs.
Wine bottle dares on the shelf (using FastLED) the other is the VarSpeedservo example program / Sweep TowServo.
