Design a clock, timer or counter into your next project using this pretty 4-digit seven-segment display. These bright crisp displays are good for adding numeric output. Besides the four 7-segments, there are decimal points on each digit and an extra wire for colon-dots in the center (good for time-based projects) and a top right hand dot which could be...
This a well designed, Arduino compatible mobile robot development platform,you can build it and program it easily with tons of published free codes. Compare with the last mobile platform, this one has a light body with mounting holes, you can add Variety of sensors to make it more interesting.
This is a digital temperature sensor, that is already calibrated. The measurement is done where the sensor is, no need for long insulated wire or complicated ADC design.
This sensor is therefore also perfect for use with a Raspberry Pi, as it is not analogic, all the data is transmitted in digital One Wire protocol.
