I was messing around with a personal project today (that’s what weekends are for, after all!), and was trying to get the current consumption on a small wireless board as low as possible in power-down mode (to keep the thing running for years of a single battery). I trust my Agilent 34410A, but measuring very low current can be a challenge, and I thought it was a good excuse to try out the uCurrent I picked up a while back from the shop here. $1400 DMM versus $60 red box, and the results were bang on. If you just need to accurately measure current, the uCurrent will definately leave a much smaller hole in your wallet without compromising on accuracy or reliabilty!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. 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 code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. 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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
