Has anyone ever got the CH224K to work correctly? For some reason it doesn’t seem to be able to request voltages above 9V. Only 5V and 9V are possible.
I want to know when the batteries of a model are getting low. The 5 AA batteries are over 5 volts so I cannot check the end voltage. I make […]
hey, I’m experiencing intermittent power-on failures on my ESP32-WROVER-B dev board after connecting external peripherals, including a BME280 temperature and humidity sensor, MPU6050 accelerometer and gyroscope, 5V DC motor controlled […]
Latest step in a MIDI drums project: Displaying MIDI inputs to an Arduino Opta w/ an SSD1306 OLED and my AUX adapter device https://www.tindie.com/products/35482 Wasn’t too hard to get the […]
I’m using a circuit that gives a LOW output on D when a magnet passes by the reed switch. Is there a way to make it output HIGH instead? (HIGH […]
Hey everyone, I’m currently working on an electromagnetic flow meter project and have finished the assembly, including the electrodes and Faraday cage. Now, I’m moving on to the circuitry, but […]
Related question: I’ll likely use an ATtiny85 for this project, meaning limited IO pins (WIP schematic pictured). I’ll mostly be listening for signals with a software serial Rx pin, but […]
What do you guys usually use as your go-to IoT platform? I’ve been working on an Arduino presentation involving their Pro line and just between us… (as much as one […]
Those of you that use a CR2032 battery, have you ever looked at the datasheet? Per this one https://www.mouser.com/datasheet/2/315/3627_fileversion-1627278.pdf for instance, using just 2mA drops the capacity significantly in terms […]
