This is a set of aluminum electrolytic decoupling capacitors. Very handy for experiments and home cooked circuit board. This pack comes with 12 sets of capacitors with various capacitance and working voltage.
DFRobot analog pH meter, specially designed for Arduino controllers and has convenient and practical "Gravity" connector and a bunch of features. Instant connection to your probe an your Arduino to get pH measurements at ± 0.1pH (25 ℃).
This 7 segment LED Keypad Shield is an Arduino LCD Shield with a 4 digit 7 segment digital tube display (common cathode). It has 5 buttons that can be used as menu select buttons or control buttons, using I2C to drive the digital tube for an easy user experience.
The turbidity sensor detects water quality by measuring level of turbidity. It is able to detect suspended particles in water by measuring the light transmittance and scattering rate which changes with the amount of total suspended solids (TSS) in water.
LDRs or Light Dependent Resistors are very useful especially in light/dark sensor circuits. Normally the resistance of an LDR is very high, sometimes as high as 1000 000 ohms, but when they are illuminated with light resistance drops dramatically.
The stunning new Raspberry Pi 3 Model B has landed at ModMyPi! This third generation model maintains the same popular board format as the Raspberry Pi 2 and Raspberry Pi B+, but boasts a faster 1.2GHz 64Bit SoC, and on board WiFi and Bluetooth!
