A simple rotary encoder for all your projects.
It's like a potentiometer, but without end. It sends pulse to your microcontroller to let you know in which direction it turned. This version also has a button.
hs0038 IR sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 5V (although it seems to be OK down to 3.3V)To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen on pin 1. It doesn’t do any decoding of the signal, just passes the ‘raw data’ along.
Active Buzzer is an integrated structure electronic transducers, DC voltage supply, widely used in computers, printers, copiers,
alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products for sound device.
D-duino can be programed like Arduino. It has a display(0.96 inch OLED) so I call it D-duino. Also you can use LUA control this board like NodeMCU. You can understand this is NodeMCU+OLED. I think the 0.96″ OLED will be very helpful for makers to develop IOT.
Chem-Wik® Rosin is especially designed for today’s heat sensitive electronic components. The lighter mass, pure copper braid construction allows for better thermal conductivity, even at low temperatures. Chem-Wik® Rosin responds as much as 50% faster than conventional desoldering braids. This design minimizes overheating and requires less “contact”...
