This instructables show how to use a square color display and Arduino dev board build a watch core. This will cover the topics of dev board selection, display selection, extra modules selection, UI design, performance tuning and power saving. Note: I have prototyped some Arduino Watches few years ago. But the hardware sizes at that […]
I have in my hand a distance laser sensor with high precision and speed. It is used in industrial environments for object positioning or detection applications. According to technical documents, I found it can communicate with other devices via RS485. I spent the weekend to learn it and find ways to communicate with cheap CPU […]
Today I will share how to make a WIFI JOYSTICK from an ESP8266 and 4 ways industrial joystick. It can be integrated into the factory’s automation system or be used for smart home control. The mentioned control systems are PLCs and the specific case that I am applying is SIEMENS PLC S7-300….. Let’s start and […]
What are we building? Humans can’t detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic […]
Which uses more water – a bath or a shower? I was recently thinking about this question, and I realized that I don’t actually know how much water is used when I shower. I know when I’m in the shower sometimes my mind wanders, thinking about a cool new projects idea or trying to decide […]
This instructables show how to start playing with TTGO T-Watch. Step 1: What Is TTGO T-Watch? TTGO T-Watch is watch shape ESP32 based development kit. 16 MB flash and 8 MB PSRAM both are top specification. It also built-in a 240×240 IPS LCD, touch screen, micro-SD card port, I2C port, RTC, 3-axis accelerometer and a […]
Relive the fun of early computer game music with an authentic 8-bit chiptune synthesizer, which you can control over MIDI from the comfort of any modern DAW software. This simple circuit uses an Arduino to drive an AY-3-8910 programmable sound generator chip (or one of its many clones) to recreate that 1980’s sound. Unlike the many designs […]
As a motorcycle rider, I’m all too familiar with being treated like I’m invisible on the road. One thing I always add to my bikes is a top box which usually has an integrated light. I recently upgraded to a new bike and bought the Givi V56 Monokey box since it had lots of space […]
This a simple Arduino/3D printing project about colors and sounds. I made this device or as I call it ‘color instrument’ for activity for kids. It’s fun and it’s a good conversation starter about physics of colors and sound. The most interesting fact about colors, in my opinion of course, is that pink color doesn’t […]
This is the full documentation of the Autodesk University Air Quality Sensor project. Attendees at several events have participated in assembling their own air quality sensor over the past several months. The Concept to Production page will give you more information on how you can use Fusion 360 and EAGLE to create your own products with ease […]
