Wheels are easy, legs teach you something. I built a four-legged spider robot on an ESP32 with eight MG90S servos and a dedicated XL4015 power rail, then drove it from my phone over Bluetooth. Full wiring and code below.

Point a webcam at your face and two servos keep it centered as you move around. An Arduino Uno runs the pan-tilt bracket while OpenCV on your PC handles the face detection. Wiring diagram and full code here: shillehtek.com/blogs/news/ar… #Arduino #OpenCV #DIY

BEST HECKLER EVER at Mississippi Trump rally:
“Shove that ballroom up your fat ass”.
Battery sensor nodes that last months: run a BME280 on an ESP32-C3 in deep sleep, push readings over ESP-NOW to an ESP32 gateway, and it forwards them to MQTT for Home Assistant. Full wiring and code: shillehtek.com/blogs/news/es… #ESP32 #HomeAssistant #IoT

Ambilight kits cost a fortune for a strip of LEDs and code. Build your own: an Arduino Nano reads screen colors from Prismatik and drives a WS2812B strip so the picture spills onto the wall in real time. Wiring, sketch and tuning: shillehtek.com/blogs/news/ar… #Arduino #WS2812B

Want a heads up before the ISS passes over your house? I built an ESP32 and SSD1306 OLED tracker with a live countdown, rise and set directions, peak elevation, and an LED that lights when it's visible. Full wiring and code here: shillehtek.com/blogs/news/es… #ESP32 #Arduino #IoT

Build a thermal camera that spots the hot component on a board or the drafts around a window. An ESP32 reads an AMG8833 8x8 IR sensor and interpolation turns 64 pixels into a smooth heat map on an ILI9341 TFT. Wiring and code here: shillehtek.com/blogs/news/es… #ESP32 #Arduino #IoT

Wanted presence detection without a camera, so I wired an HLK-LD2450 mmWave radar to an ESP32 and served a live web page tracking up to 3 people with X/Y position, distance and speed. All local, no cloud. Wiring and full code: shillehtek.com/blogs/news/es… #ESP32 #SmartHome #IoT

Want accurate distance readings from your Raspberry Pi Pico? Wire up an HC-SR04 ultrasonic sensor and read it in MicroPython. Great for robots, obstacle avoidance, and parking sensors. Full guide: shillehtek.com/blogs/news/ra… #RaspberryPi #IoT

Two wheels, one MPU6050 gyro, and an Arduino Nano running a PID loop that catches every tilt hundreds of times a second. That is all it takes to build a self-balancing robot. Full wiring and tuning guide: shillehtek.com/blogs/news/ar… #Arduino #Robotics #DIY

Want live room temp and humidity in Home Assistant? Wire a DHT11 to an ESP32 and publish over MQTT with PubSubClient. You get dashboard gauges, history graphs, and automations. Full wiring and code: shillehtek.com/blogs/news/es… #ESP32 #HomeAssistant #IoT

🤔If the “news” reports that everyone will get $5,000 checks if Republicans win the midterms, does that make them “fake news?”
If it is real news, does it mean Republicans are running “against socialism” or “for socialism?”
That 16x2 LCD can do more than print text. createChar() lets you define your own 5x8 icons, so you can build a smooth 80 step progress bar and a little walking animation on an Arduino Uno with an I2C backpack. shillehtek.com/blogs/news/ar… #Arduino #Electronics

Classic first robot build and still one of the best. An Arduino Uno, an HC-SR04 on a servo and an L298N driver is all it takes. The servo sweeps, the code picks the clearer side, and the robot drives itself around anything. shillehtek.com/blogs/news/ar… #Arduino #Robotics
