STM32F103 Bootloader and programming

This time I bring you a guide about STM32F103 (Bootloader and programming). This microcontroller has the advantage of having more capacity on almost everything compared with an Arduino (ATMega328p), having more SRAM, program memory, ADC and DAC resolution... for a little more money. More info into the Datasheet. STM32F103_datasheetDownload Furthermore…

ArduMenu: Create menus on Arduino or ESP8266

Today I bring you a module that I have created, which will allow you to create menus for your Arduino and compatible ones, such as ESP8266. Currently it is only compatible with two displays: Nokia 5510 (PCD8544) and those that use the ST77XX chip, with the Adafruit libraries. In the…

Temperature and humidity: Arduino & DHT11/DHT22

Today I bring you a tutorial on how to mount a temperature and humidity sensor with Arduino, using the DHT11 or DHT22 temperature sensor, and the Nokia 5110 display. When doing the project, I focused on consuming as little as possible, since nobody likes having to change the sensor batteries…
