Electronics Starter Kit: Breadboard, Power Module and Loose Parts
A boxed set of the parts most breadboard circuits start with: an 830-point breadboard, a USB-C power module switchable between 3.3 V and 5 V, jumper wires, resistors, capacitors, LEDs, buttons, potentiometers, diodes, transistors, MOSFETs and two sensors. How to read the parts, set up the bench, and build the first circuits.
Dual Bright LEDs
Two 5730-size white LEDs on a TinkerBlock board, one warm (3000K) and one cool (6500K), each switched by its own S8050 transistor with a 10 Ω resistor from VCC. A pin for each colour, PWM for brightness and for every white between the two. VCC may be 5 V on a 3.3 V board; on 5 V, cap the PWM at two thirds.
Infrared Transmitter
A 5 mm, 940 nm infrared LED on a TinkerBlock board, switched by an S8050 transistor, with one 150 Ω resistor setting its current from VCC and a red LED that shows when it is on. SIGNAL HIGH turns it on. Your pin only feeds the transistor, so VCC may be 5 V on a 3.3 V board. Blink it, send remote-control codes to a TK15, or make a break-beam with a TK64.
