This project is a smart, Arduino Nano-based automatic liquid dispensing system. It uses a water pump, solenoid valve, and flow sensor to control the amount of liquid dispensed. A Nextion display is ...
[Instrument Tek] isn’t messing around with a hobby-sized greenhouse. In fact if it were any bigger we’d call it a commercial operation. But what interests us is the professional-quality greenhouse ...
I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...
The Silicon Labs Si4735 is a single-chip solution for receiving AM, FM, and shortwave radio. With a bit of hacking, it even supports single sideband (SSB). All you’ve got to do is provide it with a ...
Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...
In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a laser pointer. The following is excerpted from the ...
Man, do nerds love their coffee. How else do you explain that a robot-controlled espresso machine blew through its Kickstarter target by a crazy 16X? Coffee-loving engineers Gleb Polyakov and Igor ...
Want to know how to interface an Arduino with a Radio Control Transmitter? Read on to see how. Signals from the Arduino can be sent to the transmitter as a result of this interface. The arduino signal ...
