![]() ![]() ![]() Join us every Wednesday night at 8pm ET for Ask an Engineer!įollow Adafruit on Instagram for top secret new products, behinds the scenes and more ĬircuitPython – The easiest way to program microcontrollers – CircuitPython. You can use a simple wire bridge for that. You need to additionally wire up the board’s IO1 pin with the board’s pin 6. For data, we can use any of available digital pins, see here Use an addition 4.7k resistor between +3.3V and the data line. Connect the one wire temperature sensor DHT22 to Adafruit. Wire.begin(0, 2) on ESP-01, else they default to pins 4(SDA) and 5(SCL). Temperature Sensor using Adafruit Feather 32u4 and DHT22. Before using I2C, pins for SDA and SCL need to be set by calling Wire.begin(int sda, int scl), i.e. ![]() Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there. I2C (Wire library) Wire library currently supports master mode up to approximately 450KHz. Join 35,000+ makers on Adafruit’s Discord channels and be part of the community! A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand. ![]() It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. ![]()
