Need a specific value current sense resistor, perhaps to customize your INA219 DC current sensor? This handy 1% 2W 2512 resistor kit from Stackpole may come in handy. It’s not particularly cheap ($84 USD), but it’s still a very good value since it includes 25 each of 27 different resistor values between 0.0005 and 0.75 ohms (675 total), and many of those resistors are around $1 a piece in single quantities.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
