In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

User [mircemk] presents his “MiliOhm Meter” project which you can build with an Arduino, a handful of common parts from your lab, and a cigar box. It doesn’t get much simple ...

Made a simple Arduino circuit with a 16*2 LCD screen and LED as outputs, 5 buttons, and 2 analog switches as controls. Calculator - does simple calculations (addition, subtraction, multiplication, ...

The Casio SK-1 keyboard is fairly well-known in the “circuit bending” scene, where its simple internals lend themselves to modifications and tweaks to adjust the device’s output i… ...

This article follows up by presenting a simple circuit for a frequency counter derived from the GPSDO schematic. As shown in Figure 1, we reuse much of the previous design including the power supply, ...

Transmitter Section The circuit diagram is simple and easy to understand, but assembling it can be a bit challenging. Below, you can see the circuit diagram for the Smart Helmet transmitter side. Here ...

Circuit Diagram 1. Servo motor: connected to pin 7 on the Arduino. 2. LDR1: connected to analog pin A0. 3. LDR2: connected to analog pin A1. 4. Use two 10kΩ resistors to create a voltage divider for ...

A few of resistors and capacitors “condition” the audio signal. The left-hand side of the schematic includes the Arduino Uno’s ATmega328 and the components located on the Extension Shield. At the ...
