Hello, I wanted to try these ST7735 inexpensive displays that can be found all over the internet, so I ordered a couple for a few euros each. My quick research showed that a number of libraries support them and it turns out that you can
Hi all, I know I haven’t updated my blog for a long time. Apologies. This is is because of spending time with my family and work. I’ll try to post small guides from time to time. This Christmas I wanted to play a little bit
Sharp 2Y0A710F is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector) , IRED (infrared emitting diode) and signal processing circuit. The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced
MAX7219/MAX7221 are compact, serial input/output common-cathode display drivers that interface microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. If you want to connect a few of these cheap led matrixes that are based on MAX7219
New kid on the block. ST Microelectronics joined forces with Arduino and they delivered the a model with the code name Arduino Star Otto (ARD-OTTO-STM32). It is the first board that includes high-performance graphics, display support, and Wi-Fi link to enable users to create connected systems
When you are in a need to control or measure just one thing and there are no high expectations in speed or memory there is absolutely no reason to use a microcontroller like Atmega328p(the one you can find in Arduino Uno). You should consider the ATTiny85
So if it happens to be the owner of the very first esp8266 modules, the Esp-01’s, you already know that it is not that simple to physically connect them to an arduino board due to pinout. You will need either to bend the pins to
The last few nights I am playing with an Esp8266 module that I had laying around for months and never connected it to my local wifi. Its one of the first modules, the ESP-01. The plan was to connect it to an Arduino mini
Have you ever wanted to make your own coin-operated arcade game cabinet, jukebox, or claw machine? Rachel Weil walks through how to wire up and write code for an Arduino and a programmable coin acceptor. [00:40] Review of materials needed [02:42] Setting up the coin acceptor [04:02]
Espruino Pico is a tiny USB stick that runs JavaScript code (it doesn’t need to be plugged into a computer). You can program it with nothing but a serial terminal program, but there’s also an IDE that runs in the Chrome Web browser. It’s got
