USB Serial + Li-ion Battery Charger
Mackey Jan 06,2020
Many projects need both USB Serial and a single cell Li-ion battery charger. A lot of the serial and charger modules aren't easy to mount in an enclosure. This board can be mounted with the component side up or down. The Tx, Rx, Standby, and Charging LEDs can be soldered to either side of the board. In both of the photos the LEDs are mounted on the opposite side (not visible in the pictures.) The USB connector extends from the side of the board allowing the board to be mounted on slightly c...

LoRa E32 Series device WeMos D1 mini shield RF 8km range
Mischianti Jan 06,2020
LoRa or Long Range wireless data telemetry is a technology pioneered by Semtech that operates at a lower frequency than NRF24L01 (433 MHz, 868 MHz or 916 MHz agains 2.4 GHz for the NRF24L01) but at thrice the distance (from 3000m to 8000m).You can find It hereAliExpress (3Km) - AliExpress (8Km)We are going to test E32-TTL-100. It is a wireless transceiver module, operates at 410 441 MHz based on original RFIC SX1278 from SEMTECH, transparent transmission is available, TTL level. T...

Password Door Lock Security System using Arduino and Keypad
Fahad Jan 04,2020
in this tutorial, you will learn how to make the most efficient Password protected door lock security system using Arduino and a keypad. When you enter the correct 4 digit password the door is opened for 5 seconds. Currently the password is 1234, which you can change in the programming; you can even select a password consisting of more than 8 digits. I have checked this Password Door Lock Security System many times and it worked perfectly. If a wrong password is entered 3 times the person is loc...

The Mini USB ArduinoThe Arduino Mini USB is designed to be a small, compact-size Arduino using the Attiny85 Microcontroller as shown in Figure 1.Its purpose is to make programming easier, avoid the use of recording cable, and be small in size. applied to projects that require a small control circuit.The Attiny85 Microcontroller can be programmed directly through the computer's USB. Hereby we place a USB connector directly on the printed circuit board. This will make recording easier and will pre...
