HC-SR04 ultrasonic echo connects to pin D3 on Arduino Nano. This device receives the bouncing pulse to get the distance between the food dispenser and the obstacle. It measures how long it took the pulse to travel and, using the speed of sound, we calculated the distance. SG90 servo conne...
Now as for the position sensor, the simplest solution is to use a simple potentiometer just like the one we saw in the RC servos. The problem with these types of potentiometers though is that they have a limited range of rotation of only 270 degrees, which directly limits the range of ...
How to Make a Runaway Cookie Box: Eat too many cookies? These are some guidelines for how you can add a few security features to an ordinary box of cookies - or at least have a fun toy. The runaway cookie box will roll away when objects approach it and
If you hook a narrow band 760us center servo up to a 1500us or 1520us output, the servo likely won't work at all. If you hook a 1500/1520us servo up to a narrow band 760us output, the servo can be damaged because it will overtravel and stall. I get so many questions from peo...
Flapping wings produce lift and thrust in bio-inspired aerial robots, leading to quiet, safe and efficient flight. However, to extend their application scope, these robots must perch and land, a feat widely demonstrated by birds. Despite recent progress,
Here’s an example of how you can connect this circuit to a breadboard: Arduino Hall Effect Sensor Test Code To test the Hall effect sensor, you need to read the output pin, which is connected to Arduino digital pin 2. So basically all you need code-wise to read out the value ishall...

Before attaching the head to the mechanism we need to preassemble it, or attach the mandibles with the small SG90 servo and the ultrasonic sensor. Again it’s a bit tight here but I still managed to insert the first mandible and secure it to the head using a M4 bolt. ...

Arduino is a board with amicrocontrollerthat can easily be programmed from the Arduino IDE. Amicrocontrolleris a small chip with several input and output pins. You can write code, for example, to set an output to be HIGH or LOW. And if you connect aLight-Emitting Diode (LED)to that outp...
