Solder the amplifier circuit, dead bug style.Solder the speaker output of the Bluetooth headset to the 100 Ohm resistor. Cut the heat shrink tube to cover,Solder the resistor now to pin 2 of the TransistorSolder pin 3 of the Transistor to the Power connection...
Greetings fellow Enthusiasts Let me introduce myself. I'm Bones MacGyver. I like to make sparks.I'm going to do my best to help out the community with their battery woes.By no means am I a battery expert. But I have used and abused MANY Ni-Cd cells (and...
Winding the inductors is easier than you might think! I used about 4 feet of 18GA Magnet wire to wind the inductors for this particular power supply. Each inductor has ~30 turns on it for an inductance of about 90uH. If you don't have...
In this step, how the Arduino shield stack gets assembled, and how to wire your wave shield will be discussed. If you remember the note from the top in step 1, You hopefully used stacking headers to build your wave shield. If you didn't,...
Cannon code- #include "Servo.h" // include the servo library Servo armServo; // servo to raise the arm Servo cannonServo; // servo to recoil cannon // these constants won't change: const int triggerSensor = 1; // the sensor is connected to analog pin...
Make Processing control Arduino THE FINAL PROGRAM:So,you have started drawing on Processing. Now, you'll 'feel' the drawing!Imagine you are blind (remember, this device was invented for blind people to draw on computers):How would you feel a raised line...
Power to Servo motor So, we've written the code. Now start all wiring stuff:We have two options:Give 5V to servo motor from Arduino.Here, you can connect the servo motor ( attach a small fan to the motor ) to Arduino Uno. Servo motor has 3 wires: Connect...
For this step you will want a variac or some way to limit the mains current. You might want to put a lamp in series with the hot wire to the transformer (are you sure you're comfortable working with mains electricity?)Connect everything up as you did...
