Ultrasonic Range Finder with an ATtiny85 (With Shield)

I’m here to show you how to use a HC-SR04 Ultrasonic Range Finder with an ATtiny85 as well as programming the ATtiny85 using the wonderful shield that randofo created.

List of materials:
ATtiny85 Programming Library
Arduino Uno
HC-SR04 Ultrasonic Range Finder and Library
Jumper Wires
Breadboard
ATtiny85

Step 1 Program the Arduino

Before you connect your shield to the Arduino Uno, you’ll want to make sure you’ve put your Arduino Uno into it’s ISP mode, to do this load up your Arduino IDE and once it’s loaded go to File > Examples > ArduinoISP, now connect your Arduino up to your PC and upload the ISP sketch.

where can i purchase jumper wires like the ones shown??? Ive been looking for sooo long. Thanks in advance

[diy_bloke]

Dealextreme has them as well. good quality and very cheap

Sparkfun.com will have jumper wires, the ones I'm using are from Earthshine Electronics

what does this contraption do?

A useful application would be in the drone community or other RC flying platforms.

Well the base of this project is for you to do something when an object or something else gets within a certain range, other than that it's only limited by your imagination and I/O pins

Could you suggest something that I can put behind my car to give warning when I am reserve driving

I wrote a short program that uses if_then_else statements to determine and energize one of three LEDs (green, yellow, red) depending on the distance and installed it on the back of my motorhome. Works great. I even ended up using an RGB (3n1)led to minimize the footprint. I used inches and the light stays green until 3ft then goes to blinking yellow until distance is less than 2ft. THEN red. One NOTE: the HC-SR04 is voltage sensitive and must not exceed the rated 5vcc. Unlike the arduino that can handle some variations. Its and expensive lesson.

some autobody shops sell ultrasonic parking guides, I'd advise you go check those out, I'm not sure that this could do the job.

Adafruit.com also has them. They have both male: https://www.adafruit.com/products/153 and female: https://www.adafruit.com/products/266.
