Arduino Nano 33 BLE OV7670 Camera Shield

“Embedded machine vision board, make your robotics ML enable. Arduino Nano 33 BLE processing capacity is moderately high for the low power consumption embedded system. Since it has many sensors on board, it seems to be very fun to run …

Arduino Psychic

“This is a magic trick done using two Arduinos. One Arduino is a random# generator, the other Arduino will identify a random # chosen by the audience. Please watch the video. It’s easier shown than explained. :-( Supplies: Any two Arduinos …

Automatic Watering System for My Plants

“When the soil is dry, Arduino will command the water pump to run. Our plant is absolutely cheerful anytime! This is my first project. I love plants, so I created an automatic watering system. Our system measures the soil moisture …

Chang’e 5 sets out to collect moon samples in landmark mission

“China launched a large robotic spacecraft early Tuesday morning at the Wenchang Space Launch Center in South China’s Hainan province, tasking it with landing on the moon and bringing back lunar samples, 44 years after the last time such …

Coil Winder Using Arduino

“Why this project was built? I work at Prabal Learning Innovations, an educational startup. One of our educational kits contains a 3D printed part that is wound with a copper coil to demonstrate electromagnetic induction. Winding the 3d printed part …

Create Apps for the ESP32 Using BLE Through P5

“The ESP32 is cool, but it is cooler when you can make your own apps for it. In this tutorial, we will guide you to use BLE-UART to do so. Story It is quite tricky to get Arduino (and …
