I recently bought two MakerHawk RF Wireless 868 MHz LoRa modules, which are actually EByte E32 868T20D types. The E32 series is based on the SemTech SX1276/SX1278 RF IC from SEMTECH with transparent transmission and LoRa spread spectrum technology. EByte provides datasheets and product specs, but there is no library for Arduino or whatever. After ..
Introduction The idea behind a battery powered night light came from my realization that my bedside cabinet was already cluttered by a few electrical appliances, like a lamp, a radio, and a smartphone power adapter, and fumbling around while searching the light switch usually caused something to drop onto the floor. A night light usually ..
Introduction The Espressif ESP8266-01 module is known for the excessive load it can incur on a circuit. This is particularly true when the module boots up and connects to a WiFi network. This load easily exceeds what the Arduino Pro Mini can provide through its builtin voltage regulator. I destroyed my Arduino module because I ..
Introduction The Espressif ESP8266-01 module is dirt cheap but only has two (four if you don’t need Tx/Rx) digital pins and no analog pins. Nevertheless, it still has its usage if you only need digital I/O. You can control up to four actuators via the digital pins (GPIO set to output) or control the status ..
Introduction The Arduino MKR1000 module contains a wealthy lot more SRAM than the Arduino UNO or even MEGA. This, and its 3.3 V base voltage makes it the ideal platform for using it with the Waveshare 1.54 Inch E-Paper Display Panel Module. This article describes how to connect the display module to the MKR1000 and run ..
